Chain Hoist Roll-Up Door Installation Instructions
Step-by-step installation for SB3 chain hoist roll-up doors — spring-loaded doors operated by a hand chain, built for larger, heavier openings where a manual pull-down door would be too much to handle. These instructions cover both bug screen and vinyl roll-up doors; the hardware and mounting are identical, and only the curtain material differs.
This guide covers the full chain hoist install: mounting the tracks, tensioning the spring, seating the roll on its bearings, and mounting the chain hoist and friction brake. It works alongside the printable mounting-style PDF that shipped with your door — always follow the exact fastener sizes, clearances, and spring turns in your PDF.
No electrician is required — chain hoist doors are fully manual. For powered doors, see the other roll-up guides below.
Step 1: Choose Your Mounting Style
Chain hoist doors mount one of three ways. Because the roll is driven by an external chain hoist hung off the side, the assembly projects out past the opening, so an in-jamb (under-lintel) configuration isn't possible. The spring, roll, chain hoist, and header steps below are shared — only the track attachment differs. Pick the one that matches your opening, then download its printable guide.
E-Track Mount
The Gateway track fastens flush to the back of an existing rolling-steel door's track, so the screen's flat-stock side projection sits flat against the back of that door. The door is built so the out-to-out (OTO) equals the width of the existing door. This is the choice when you're adding a chain hoist door behind an existing rolling steel door.
Stand-Off Mount
Stand-off brackets fasten directly to an existing sectional or overhead door's track (or its reverse angle). Each track uses a minimum of four stand-off brackets, and the screen's out-to-out is set to the Gateway track OTO on your order. Best when a sectional door is already in place and you want to add a chain hoist screen in front of it.
Wall Mount
The tracks fasten flat to the wall face on either side of the opening; the door is built about 8″ wider and taller so all the hardware clears and retains the full opening. Wall mounts use track mounting clips to anchor the tracks to the wall, and the chain hoist end mounts on the side documented on your order sheet with the idler end opposite.

Know the Parts of Your Chain Hoist Door
The chain hoist roll-up shares the same curtain and roll assembly as our other doors, operated by an external hand-chain hoist with a friction brake. The mounting bracket varies by mount style (E-track bracket shown; stand-off brackets or wall track clips on the other mounts).
- Chain Hoist & Friction Brake — the hand-chain operator that raises and lowers the door and holds it in position; the friction brake controls how smoothly it moves.
- Spring-Loaded Roll Tube & Football Bearing — a spring-loaded tube the curtain rolls onto, riding on a 1″ keyway shaft captured by a football bearing bolted to the mounting plate.
- Roll Tube Mounting Bracket — supports each end of the roll tube (chain hoist end and idler end).
- 6″ Brush Seal / Automatic Reset System — keeps the curtain seated in the track and resets it after impact.
- Windbar & Pocket — horizontal stiffener that holds the curtain flat against wind.
- Curtain — insect-screen mesh or reinforced vinyl, depending on your door.
- Aluminum Tracks, Vinyl Weatherstripping & Bottom Foam Cushion — guide the curtain and seal the sides and floor when closed.
Before You Begin
- Inspect the shipment — note any crate or packaging damage on the freight paperwork before signing; exterior damage can hide concealed damage. Verify all parts against the packing list.
- Leave the stretch wrap on — do not remove the plastic/stretch wrap around the door until it's installed, or the roll will unroll.
- Verify dimensions — confirm the door width and height against your order (wall mounts run about 8″ taller and wider), and check that the opening is square.
- Confirm the mounting surface — rolling-steel track, sectional track, or wall must be sound and use the correct fasteners for the material.
- Plan the chain drop — make sure there's a clear run for the hand chain and a spot on the wall for the chain keeper, roughly 3–4 ft off the floor.
Required Tools
- Tape measure and level (4 ft recommended)
- Crescent wrench for spring tensioning
- Drill / impact driver and bits sized to your fasteners
- Socket / wrench set and appropriate anchors for your surface
- Fasteners per your mounting style — the PDF lists exact sizes (e.g., 3/8 × ½ bearing bolts with nylock nuts, ¼-20 × 1″ header-angle screws, 5/16 × ¾ stand-off bolts, 10 × ¾ clamp-strip screws, 2.5″ sheet-metal screws to secure the roll tube)
- Ladder or lift rated for the opening height, plus a helper
Step 2: Mount the Brackets & Tracks
Follow the fastener sizes and clearances in your mounting-style PDF.
- Set both tracks per your mounting style — level, flush with the floor, and diametrically opposed and parallel. Mount the chain-hoist-end track on the side documented on your order sheet and the idler-end track opposite.
- Connect the top header angle (2″ × 2″) across the tops of the tracks with the provided ¼-20 × 1″ screws, so the brush-seal retainer faces the door and acts as a top seal.
- Attach the side screens to the tracks, and don't let any fastener impinge on the track operation.
Step 3: Tension the Spring
Chain hoist doors are spring-counterbalanced. With the curtain wrapped tightly on the roll tube, slide the flat retaining plate off the spring end, then wind the square shaft clockwise with a crescent wrench using the turn chart. Replace the retaining clip to lock the spring until the roll is installed.
Wind clockwise only, a maximum of 25 complete turns. On wall mounts, if the spring is on the left, rotate clockwise; if it's on the right, rotate counter-clockwise. Springs wound the wrong way or past 25 turns aren't covered by Gateway without prior approval and can detach.
Step 4: Mount the Roll & Chain Hoist
Seat the idler (notched) end into its bracket until it fully seats, unroll about 1.5 ft of curtain to hang in the track, then install the tensioned spring end and remove the retaining clip. Fasten the football bearing to the slotted plate with the 3/8 × ½ bolts and nylock nuts, slide a shaft collar against the bearing, and tighten to hold the roll in place.
Slide on the sprocket with its keyway and the chain hoist assembly — small sprocket down, facing the big sprocket — then the last collar. Run the hand chain up through the bottom front of the hoist by turning the small sprocket counter-clockwise, trim it to length, and connect the ends. Install the roller chain around both sprockets, and fasten the chain keeper to the wall about 3–4 ft off the floor so it doesn't interfere with the hand chain.
Orient the hoist so the friction brake is on the right side. Adjust the tensioning nut to set the brake: compressing the spring tightens the brake, so the door opens and closes smoothly and holds its position when you let go. With the door down and in place, drive the 2.5″ sheet-metal screws through both mounting plates to lock the roll tube. Failure to secure the roll tube can cause injury.
Step 5: Mount the Header Curtain
Mount the header curtain to the wall with the aluminum clamp strip, using the 10 × ¾ screws in every other hole so the top of the clamp strip sits about 1″ above the top of the roll assembly. Make sure the curtain hangs down in the track against the back of the roll, Gateway logo facing the building exterior.

Safety Notes
- Leave the stretch wrap on until the roll is fully installed, or it will unroll.
- Wind the spring clockwise only — a maximum of 25 complete turns. Never let go of the wrench while the spring is under tension; it can spring back and cause injury.
- Orient the friction brake on the right side and set the tensioning nut so the door is easy to control.
- Secure the roll tube with the 2.5″ screws before operating the door.

Chain Hoist Roll-Up Installation FAQs
What is a chain hoist roll-up door for?
Chain hoist doors are for larger, heavier openings where a plain hand-pull door would be too much to lift. A hand chain turns the hoist to raise and lower the curtain, and a friction brake holds the door wherever you stop it — all without power.
Do bug screen and vinyl chain hoist doors install differently?
No. The hardware, tracks, spring, chain hoist, and mounting are identical. The only difference is the curtain — insect-screen mesh or reinforced vinyl — so a single install process covers both.
Do I need an electrician for a chain hoist door?
No. Chain hoist doors are fully manual — operated by a hand chain and friction brake — so there's no wiring and no electrician required.
Why is there no in-jamb mount for chain hoist?
The chain hoist hangs off the side of the roll and projects out past the opening, so the assembly can't tuck into a jamb. Chain hoist doors mount by E-track, stand-off, or wall only.
How many turns should I wind the spring?
Use the turn chart for your door's width and height — most doors fall between 8 and 14 turns. Wind clockwise only, and never exceed 25 complete turns.
How do I adjust how easily the door opens?
Set the tensioning nut on the chain hoist. Compressing the spring tightens the friction brake; when it's adjusted right, the door opens and closes smoothly and holds its position when you let go of the chain.
What's the lead time and warranty?
Typical lead time is 3–4 weeks, and 3–5 weeks for one to two doors during peak summer demand. SB3 doors carry a 1-year limited warranty covering defects in materials and workmanship from shipment.
