Don-Jo ALP-210-SL – Frequently Asked Questions

1) Will the Don-Jo ALP-210 latch protector work on an inswing door?
No. The ALP-210 is an angle-type protector built for out-swing doors, where the latch and strike gap are exposed on the pull side and vulnerable to prying or shimming. On an inswing opening the latch edge faces away from the attacker, so an angle protector is the wrong part; you would be looking at a flat or LP-type protector for the strike side of the frame instead.
2) How does the Don-Jo ALP-210 mount, and does it need to be cut into the door?
It mortises directly into the edge of the door rather than surface-mounting over the face. That means routing a pocket in the door edge for the 1-1/2 x 10 inch plate so it sits flush. Plan on a router or a good chisel and a door you are allowed to cut into. If you need something that goes on without machining the door, a surface-applied latch guard is the direction to go.
3) What size is the Don-Jo ALP-210 and will it cover my latch area?
The plate measures 1-1/2 inches by 10 inches, which puts about five inches of steel above and below the latch when you center it on the latch centerline. That covers the latch and the gap either side of it on a standard commercial lockset. Measure your door edge first: on a narrow-stile aluminum door there may not be 1-1/2 inches of edge to mortise into.
4) How thick is the steel on the Don-Jo ALP-210 latch guard?
10-gauge steel, .134 inch thick. That is heavy plate for a latch guard, and it is what stops a pry bar deforming the protector to get at the latch. The body is steel throughout, so on exterior openings expect the coated finish to be doing the corrosion work.
5) What finishes does the Don-Jo ALP-210 come in?
Three: BC, DU (Duronodic brown coated), and SL (silver coated). DU is the one that blends with dark bronze anodized aluminum storefront and hollow metal painted dark; SL reads closest to aluminum and satin chrome trim. Since the plate sits in the door edge, the finish matters mainly for the exposed angle leg you see from the pull side.
6) Does the Don-Jo ALP-210 protect against someone shimming or prying the latch on an exterior door?
That is exactly what it is for. On an outswing door the latch and the gap between door and frame are reachable from outside, which is where loiding and prying attacks start. The ALP-210 mortises into the door edge and puts .134 inch steel across that gap so the latchbolt cannot be reached or levered. It does not replace a deadbolt or a good strike; it closes the gap the lock alone leaves open.
7) Can I order one Don-Jo ALP-210 or do they come in packs?
The ALP-210 is packed in shelf packs of 10. That suits standardizing a run of exterior outswing doors across a building rather than a single-door repair, and it is worth knowing before you order for one opening.
8) Is the Don-Jo ALP-210 rated for commercial use or is it a residential guard?
Commercial. Don-Jo builds it for high-traffic commercial door hardware, and the applications it is intended for are office buildings, schools, healthcare, retail, warehouse, multi-tenant residential, and government facilities. The 10-gauge (.134 inch) body is the reason it holds up in those settings.
