Don-Jo LP-312-DU – Frequently Asked Questions

1) Will the Don-Jo LP-312 latch protector work on an inswing door?
No. The LP-312 is built for out-swing doors only. On an in-swing opening the latch edge sits on the secure side and this guard has nothing to wrap, so you need an in-swing style latch protector instead. Check which way the door leaf travels when you push it from outside: if it swings away from you, the LP-312 is the right family.
2) Does the LP-312 fit an aluminum storefront door with an Adams Rite latch lock?
That is exactly the opening it was made for. The LP-312 is dimensioned around Adams Rite latch locks and fits aluminum storefront doors, so it covers the latch point on a typical narrow stile glass front entry without modification. Retail storefronts, office entries and multi-tenant common area doors are the usual spots for it.
3) Can I use the same latch guard on both my outswing storefront doors and my inswing hollow metal back door?
No, those take two different parts. The LP-312 covers out-swing openings only. Your hollow metal back door swinging in needs an in-swing latch protector, and if it carries a cylindrical or mortise lock rather than an Adams Rite latch, the guard geometry differs there too. Order the LP-312 for the storefront and a separate in-swing guard sized to the back door lock.
4) How much of the door edge does a 2-5/8 by 12 inch latch guard actually cover?
The LP-312 measures 2-5/8 by 12 inches, which puts roughly a foot of steel centered on the latch. That length matters on storefront doors because a pry bar attack works by spreading the gap above and below the latch, not right at it. The 2-5/8 inch dimension is what keeps it within the face of a narrow aluminum stile rather than overhanging the glass stop.
5) Is 12-gauge steel heavy enough for a latch guard on a commercial entry?
12-gauge works out to .104 inch thick steel, which is the heavy end of what gets used for latch protection and is a commercial rather than residential spec. Solid steel at that thickness resists a pry bar deforming the plate and exposing the latch again. The guard is steel throughout, not a plated pot metal casting.
6) What finishes does the Don-Jo LP-312 come in, and which matches dark bronze storefront?
Two finishes: DU, a duronodic brown coating, and SL, a silver coating. DU is the one to order against dark bronze or duranodic anodized aluminum storefront, which is the most common commercial glass front color. SL pairs with clear anodized or aluminum mill finish doors.
7) Latch protector or full door edge wrap for a storefront door being pried?
For an aluminum storefront door with an Adams Rite deadlatch, a latch protector like the LP-312 is the targeted fix: the attack point is the latch and the guard puts 12-gauge steel across it. A full edge wrap or astragal addresses gap and weather across the whole leaf and is a bigger install. If the pry damage on your door is at the latch, the guard is the part that solves it.
8) Do I have to buy Don-Jo latch protectors by the case or can I get one?
The LP-312 is packaged in shelf packs of 10, which suits a contractor or distributor stocking several storefront openings at once. Property managers standardizing a strip mall or a multi-tenant building typically use the full pack across the entry doors so every opening carries the same guard and finish.
