Don-Jo AL-211-SL – Frequently Asked Questions

1) Will the Don-Jo AL-211 latch protector work on an in-swing door?
No. The AL-211 is built for out-swing openings only. On an in-swing door the latch edge faces the secure side and this plate does nothing for you, so you would want an in-swing style latch protector instead. Check which way the door pushes from the outside before ordering.
2) How does the Don-Jo AL-211 latch protector mount, and does it screw onto the face of the door?
It does not sit on the face. The AL-211 mortises directly into the edge of the door, so it sits flush with the door profile once installed. That means you are cutting the door edge, not just drilling a face pattern, and it is the reason it works cleanly on aluminum entrance doors where a surface plate would foul the frame or the closer.
3) What size is the Don-Jo AL-211 latch protector, and will it cover a standard aluminum storefront lock area?
The AL-211 measures 3-1/2 x 12 inches, which gives you a foot of coverage along the door edge centered on the latch. On a narrow stile aluminum entrance door with a hookbolt or deadlatch, that spans the latch and the prep around it. Confirm your stile can take the mortise depth before cutting.
4) Is the Don-Jo AL-211 latch guard heavy enough for a high traffic commercial entrance?
It is 12 gauge steel, .104 inch thick, and rated by the maker as a commercial product rather than a residential one. That is the gauge you want on a retail storefront, school entrance, or multi-tenant lobby where the door gets pried at. Steel throughout, no cast or stamped light stock.
5) What finishes does the Don-Jo AL-211 come in, and will they match my dark bronze storefront doors?
Two coated finishes: DU duronodic brown and SL silver. DU is the one that reads as dark bronze against anodized bronze aluminum storefront; SL matches clear anodized aluminum. Since the plate mortises into the edge it shows as a thin line rather than a large face plate, so an exact match matters less here than on a surface guard.
6) I manage a building with several aluminum entrance doors. Can I standardize on the AL-211 across all of them?
Yes, as long as every one of those doors swings out. The AL-211 is a single 3-1/2 x 12 inch size in one gauge, so there is no handing or length to sort per opening. You pick the finish, DU or SL, to suit each entrance. Any door in the group that swings in needs a different protector.
7) Does the Don-Jo AL-211 replace the lock, or does it work with the lockset already on the door?
It is protection hardware, not a lock. The AL-211 shields the latch area of an entrance function opening against prying and latch tampering; whatever deadlatch or hookbolt is already in the door stays and keeps operating normally. Think of it as armor over the latch line, added to the existing lock.
8) Can I buy the AL-211 latch protector in a multi-pack for a whole property?
It is offered in shelf packs of 10, which is how contractors and distributors usually take it when they are doing a run of entrances rather than a single door. Finish is chosen per pack, DU or SL.
