Step 1: Decide Inside Mount vs Outside Mount
Inside mount fits the shade inside the window recess, which reads clean and lets the trim show. It needs at least 3/4-inch recess depth for a standard cassette, and 2 1/2 inches if you want the fully enclosed cassette-in-recess look. Under 3/4-inch, the bracket physically will not fit.
Outside mount attaches to the wall or the frame trim. It adds 2 to 4 inches wider on each side of the window opening, which blocks the side-light bleed inside mount can never fully close. The trade is a bracket that projects further and shows against the wall.
Roller Shade Buying Guide: Fabrics, Opacity, Motor Options
Before the bracket goes on the wall, pick the fabric tier. This guide maps room darkening vs blackout vs light filtering vs solar, and which mount fits which fabric weight.
Room function usually settles the debate. Bedrooms and nurseries lean outside mount for blackout coverage. Kitchens, bathrooms, and home offices lean inside mount for the clean look, because a little morning light there is not a dealbreaker.
Inside vs Outside vs Cassette-in-Recess
Inside mount
Fits inside recess. 3/4″ min depth. Cleanest look. Trim visible. Slight side gap on light.
Outside mount
Wall or frame. 2 to 4″ wider each side. Blocks side light. Bracket projects further.
Cassette-in-recess hybrid
Deep recess only. 2 1/2″ min depth. Fully enclosed cassette look, no exposed drum.
Warning: Outside mount width is not window width
Measuring the recess for outside mount is the most common miss. The outside mount width is wall-to-wall or frame-to-frame plus 2 to 4 inches, not the window opening itself.
Step 2: Measure the Window Recess or Frame
For inside mount, measure the recess width at the top, middle, and bottom. Use the smallest of the three, and subtract 3/8 inch per Two Pages spec sheet to leave clearance for the bracket. Rooms are rarely square, and skipping the three-point check is where install failures start.
For outside mount, measure the desired coverage width on the wall or the frame trim. Add 2 to 4 inches wider on each side of the window opening, based on how much side-light block you want. Then measure the drop from the intended bracket point down to the sill or the floor.
How to Measure for Curtains: The Complete Guide
Roller shade measurement is not curtain measurement, but the width, drop, and return rules cross over. This guide covers what to add or subtract at each mount plane before ordering custom.
Drop for inside mount runs from the top of the recess to the sill. Drop for outside mount runs from the intended bracket mount point down to the preferred bottom edge, which usually falls 1 to 2 inches below the sill for a clean cover.

Warning: Never measure once
Windows are rarely square. A 1/4-inch width variance between the top and the bottom of the recess means the shade binds on one side and drops loose on the other. Three-point width, one drop, no shortcut.
Step 3: Mark Bracket Points and Pre-Drill Pilot Holes
Outside mount leans on stud location whenever possible. A stud gives the strongest anchor on drywall, and the This Old House stud finding guide covers the tap test, the magnetic stud finder, and the electronic scanner method for when the wall reads inconsistent. Inside mount into a wood window frame skips the stud question entirely, because the frame itself is the anchor.
Where the stud misses the mark, drywall anchors fill in. The Family Handyman drywall anchor reference rates Snaptoggle metal toggles at 40 to 60 lbs, standard plastic drywall anchors at 20 to 30 lbs, and molly bolts at 25 to 50 lbs. A standard 6-foot Alvin Basic weighs 2 to 4 lbs including cassette and clutch, so a plastic anchor covers most inside-mount work and a Snaptoggle handles oversized outside mount.
How to Hang Curtains Without Drilling (Renter-Safe Options)
Renting? Tension-fit brackets, adhesive rails, and command-style hardware cap at roughly 3 to 8 lbs, which covers most standard-size roller shades but not oversized frames. This guide flags when a screwless mount is realistic.
Mark bracket points centered on the recess for inside mount. Mark level across for outside mount, verified with a bubble or laser level. Pre-drill a 3/32-inch pilot hole for a #6 wood screw or a 1/8-inch pilot hole for a #8 wood screw, matched to the anchor spec in the Alvin kit.
| Install type | Minimum depth | Recommended depth | Alvin Basic compatible |
|---|---|---|---|
| Inside mount standard cassette | 3/4″ | 1 1/2″ | Yes |
| Inside mount cordless clutch | 3/4″ | 1 1/2″ | Yes |
| Outside mount standard | N/A (wall surface) | 2 to 4″ wider each side | Yes |
| Cassette-enclosed hybrid | 2 1/2″ | 3″ | Yes |
Warning: Rate the anchor against oversized load
Plastic drywall anchors work for standard 6-foot Alvin roller shades because the load stays under 4 lbs total. On oversized frames above 60 inches wide, always double the anchor rating: switch to a Snaptoggle or land the bracket on a stud.
Step 4: Install the Brackets
Picture the drill spinning the plastic anchor loose in a 1/4-inch drywall pilot hole. Once the anchor turns freely, the fix is patching, letting the compound set, and marking a new bracket point 2 inches over. The way around that: identify bracket type and torque before the screw goes in.
The Alvin Basic ships two bracket sets in the same box. The curved cassette bracket pairs with standard roll (fabric drops off the front of the drum). The square cassette bracket pairs with reverse roll (fabric drops off the back, sitting flush against the window). Both sets ship in the box, so the choice is made at install time, not at order time.
Mount brackets level across, verified to 1/8-inch tolerance with a bubble or laser level. Screw snug into wood frame or drywall anchor, but stop before the head sinks past flush. The drive-side bracket carries the cordless clutch, and the idler-side sits opposite: identifying which side is which before mounting saves a re-drill later.
Bracket Screw & Anchor Match
🔩
Wood window frame
#6 or #8 wood screws direct. 3/32″ or 1/8″ pilot hole. No anchor needed.
🧱
Drywall, no stud
Plastic anchor + #6 screw for standard load. Snaptoggle rated 40-60 lbs for oversized outside mount.
🪛
Metal frame
Self-tapping metal screw + 1/8″ pre-drilled pilot. No plastic anchor.
Skip the Bracket-Guessing on First Order
The Alvin Basic ships with curved cassette brackets for standard roll (fabric rolls off the front) and square cassette brackets for reverse roll (fabric rolls off the back, sitting flush against the window). Both bracket sets ship in the box, so the mount choice is made at install time, not order time. All hardware, screws, and mounting anchors come pre-packed for a 15 to 20 minute install per window. Ships from stock, no lead time.
Warning: Do not over-torque bracket screws into drywall
Once the anchor spins in the hole, it is stripped. The fix is patching, letting the compound cure, and relocating the bracket 2 inches over. Snug is the target, not tight.
Step 5: Snap the Shade Into the Brackets
Align the cordless clutch with the drive-side bracket first. Slide the shade into the curved or square cassette on that side. Snap the idler-side into place until the cassette gives an audible click, which is the lock engaging.
Test the rotation by pulling the chain lift through a partial cycle. The shade should roll smoothly, no binding, no scraping. A gentle upward push on the drum confirms the cassette is fully locked and the shade will not drop out under its own weight.
If the shade rolls off the front but the room needs it flush against the window (or the reverse), the fix is a bracket swap, not a shade swap. Unscrew both brackets, swap the curved cassette set for the square cassette set from the same Alvin kit, remount level, and snap the shade back in. The Alvin Basic Room Darkening Cordless Roller Shades review covers the exact cassette identification photo, and the Two Pages Alvin install tutorial page hosts the reference video on cordless clutch alignment.

Warning: Click, not scrape
The cassette snap sounds like a click, not a scrape. If the shade scrapes on install, one bracket is 1/8-inch too low, and the shade will bind on every pull until it is corrected.
Step 6: Test Operation and Reverse Roll If Needed
Run a full up and full down cycle three to five times. The cordless clutch should hold the shade at any intermediate position with no drift, and the chain lift should feel consistent under tension. Check for a side gap on inside mount installs, and edge shadow bleed on outside mount installs.
Reverse roll orientation is a design choice, not a hardware constraint. Fabric rolling off the back of the drum sits flush against the window and blocks the maximum side light, which suits bedrooms and nurseries. Fabric rolling off the front reveals more of the drum but sits further from the window, which suits kitchens and living rooms where the shade doubles as a subtle decorative reveal.
The Two Pages Alvin install tutorial video covers the cordless clutch alignment troubleshooting step by step, which is the fastest resolution when the clutch feels loose or won’t hold position on the first test.
Warning: Do not disassemble the clutch
If the cordless clutch slips or will not hold position after install, the shade drum is over-tensioned from the factory. Two Pages ships a re-tensioning tool with each Alvin kit for exactly this case. Never attempt to open the clutch housing.
5 Roller Shade Install Use Cases
The install method is uniform. The mount type, the fabric tier, and the anchor spec shift by room. These five configurations cover the majority of Two Pages install orders.
5 Install Configurations by Room
🛏️ Bedroom
Room darkening. Inside mount for clean look, outside for full block.
🍼 Nursery
Blackout tier. Inside mount with enclosed cassette-in-recess for the sealed look.
🍳 Kitchen
Light filtering. Outside mount to clear the sill and any counter clutter.
💼 Home office
Solar shade tier. Cassette-in-recess to hide the drum from video calls.
🚿 Bathroom
Moisture-resistant polyester. Inside mount, small recess, cordless for safety.
Now You’ve Installed, Here’s the Upgrade Most Owners Regret Waiting On
The Alvin Basic Room Darkening tier blocks about 90 to 95% of light, which reads dark but not black. For bedrooms south of a streetlight, west of a low sunset, or under a nursery schedule, that last 5 to 10% is where the upgrade earns its keep at 5 a.m.
The Premium Blackout version uses the exact same bracket geometry, cassette system, and cordless clutch. The install steps transfer one for one: same screws, same pilot holes, same snap sequence, same 15 to 20 minute window. What changes is the fabric tier, which moves to 100% shading rated at 99.99% light block, and the colorway range, which expands from 13 to 19.
5 Common Failure Modes To Skip
⚠️ Screws stripped in drywall
No anchor used. Fix: Snaptoggle or stud.
⚠️ Cassette snap misaligned
Shade rolls off track. Fix: relevel bracket to 1/8″.
⚠️ Wrong cassette installed
Curved mounted, reverse roll wanted. Fix: swap sets.
⚠️ Outside mount too narrow
Side light bleeds. Fix: 2 to 4″ wider each side.
⚠️ Recess under 3/4″
Bracket won’t fit. Fix: switch to outside mount.
⚠️ Clutch will not hold
Drum over-tensioned. Fix: use kit re-tensioning tool.
The upgrade most owners install second
Now You’ve Installed, Here’s the Blackout Tier
If the room darkening Alvin lands in a media room, nursery, or west-facing bedroom, the Premium Blackout version uses the exact same bracket geometry, cassette system, and cordless clutch, so the install steps and screw points transfer one-for-one. The upgrade adds 100% shading (99.99% light block) vs the Basic’s room-darkening tier, ships in 19 colorways, and lands at from $41.39/panel. Same 15-20 minute install, no re-drilling.

Frequently Asked Questions
How do you install roller shades?
Six steps: decide inside mount vs outside mount, measure the window recess or frame, mark bracket points and pre-drill pilot holes, install the brackets, snap the shade into the brackets, then test operation and reverse the roll if needed. Total time is roughly 15 to 20 minutes per window when the tools are ready and the mount decision is made before the drill comes out. Cordless roller shades like the Two Pages Alvin Basic ship with both curved and square cassette brackets in the same kit, so the roll direction is chosen at install time, not order time.
Do roller shades need brackets, or can they attach directly?
Roller shades always need brackets. The cassette holds the drum, the clutch, and the fabric weight, and the brackets carry that load to the wall or frame. Two Pages Alvin Basic ships curved cassette brackets for standard roll (fabric off the front) and square cassette brackets for reverse roll (fabric flush against the window) in the same box. Both bracket sets require pilot holes and screws or drywall anchors. Direct attachment without brackets is not possible on any cordless or motorized roller shade system.
How much depth does an inside mount roller shade need?
Minimum 3/4-inch depth for a standard cassette on an Alvin Basic Cordless Roller Shade. Enclosed cassette-in-recess installs need 2 1/2-inch depth for the fully wrapped look. If the recess is under 3/4-inch, the bracket physically will not fit, and the only option is outside mount on the wall or frame. Two Pages spec sheets list the exact bracket dimensions for each cassette type on every roller shade product page, so the depth check happens before ordering.
How do you install cordless roller shades?
Cordless roller shades follow the same 6-step install as corded, with one additional step: aligning the cordless clutch with the drive-side bracket before snapping the shade into place. The Alvin Basic Cordless Roller Shade uses a continuous chain lift that connects to a drum-mounted clutch, not a pull cord. The clutch always sits on one bracket side, so identifying drive-side vs idler-side before mounting is critical. Once the shade snaps in, testing the clutch through 3 to 5 full up-down cycles confirms it holds intermediate positions.
Can roller shades be installed without drilling?
Only for lightweight standard-size shades under 4 lbs total. Tension-fit brackets and adhesive-mount rails cap at 3 to 8 lbs total shade weight. A standard 6-foot Alvin Basic Cordless Roller Shade weighs 2 to 4 lbs including cassette and clutch, so no-drill options work for standard windows. Oversized frames (over 60 inches wide) or blackout tiers with heavier fabric weight (191 gsm and up) always need screwed brackets with drywall anchors or wood screws. Renter setups usually pick the adhesive-mount option on standard-size windows and skip oversized installs.
How do you install outside mount roller shades?
Outside mount brackets attach to the wall or the window frame trim, not inside the recess. Measure the window opening width and add 2 to 4 inches wider on each side to block side light bleed. Locate wall studs where possible for the strongest hold. Between studs, Snaptoggle metal toggles rated 40 to 60 lbs or plastic drywall anchors rated 20 to 30 lbs handle a standard roller shade weight. Pre-drill pilot holes matched to the anchor spec, mount brackets level across to 1/8-inch tolerance, then snap the shade in as normal.
Why won’t my roller shade snap into the bracket?
Three common causes. First, bracket misalignment: if one side is 1/8-inch too low or too high, the cassette will not seat flush and the shade will bind on every pull. Verify level along the full run. Second, wrong cassette shape: the Alvin Basic ships curved and square cassette brackets, standard roll needs curved, reverse roll needs square, and mixing them means the snap will not engage. Third, the shade drum is caught on debris in the bracket, clear the bracket, wipe the drum end, retry the snap.
How do you reverse the roll direction on a roller shade?
Unscrew both brackets, swap the curved cassette bracket set for the square cassette bracket set (both ship in the Alvin Basic kit), remount level, then snap the shade back in. There is no way to reverse the roll without swapping brackets: the cassette shape determines the fabric roll direction. Standard roll (curved cassette) drops fabric off the front of the drum, reverse roll (square cassette) drops fabric off the back, sitting flush against the window for maximum side-light block. The Two Pages Alvin install tutorial page hosts a video showing the cassette swap.
