Steel Door Units with Vision Lite — 10×10 Window Kit
Steel Door Units with Vision Lite10×10 Window Kit Installed
A complete steel door unit with a 10" × 10" vision lite, so people can see who's on the other side: a 20-gauge door, a 16-gauge welded or knock-down frame, spring hinges and a UFD knob or lever lock, with the window cut and installed in our shop.


A window that's done right
Every vision lite unit starts from our complete door unit — door, frame, hinges and lock — with a 10" × 10" lite kit installed before it ships. Vision lite units are priced by quote.

Welded or knock-down?
Throat depth is the overall wall thickness the frame wraps. Pick the frame type, then the throat that matches your wall.
Welded frame
One rigid piece with welded corners, set as the wall goes up. The strongest option for masonry and concrete block walls and new construction.
Masonry & block wallsThroat: 4 7/8"Knock-down frame
Ships in three pieces and wraps a finished drywall opening — ideal for retrofits and tenant fit-outs. 3 3/4" fits 2-1/2" studs, 4 7/8" fits 3-5/8" studs (5/8" drywall each side), 6 1/8" fits thicker walls.

Fewer collisions
See who's coming before you push the door open — key in corridors and kitchens.
No field cutting
The lite is cut and installed in our Brooklyn shop, so it arrives ready to hang.
Fire-rated openings
Tell us if the door needs to keep its fire rating and we'll quote the right glass.
How to pick the right swing

Stand on the outside of the opening — the side the door swings away from.
Right hand: hinges on the right, door swings away from you.
Left hand: hinges on the left, door swings away from you.
Reverse (RHR / LHR): the door swings toward you — call us if you need a reverse swing.
Measuring: order by nominal door size. A 36" × 80" unit has an actual door of about 35-3/4" × 79-1/4" and an overall frame of about 40" × 82". Check your drawings or local code for the required swing — or send us your rough opening and we'll confirm.
Send us the opening. We'll quote it today.
Tell us the door size, frame type, lock and whether the opening is fire rated. We'll send an itemized price.
