Don-Jo LP-2878-PC – Frequently Asked Questions

1) Will a Don-Jo LP-2878 latch protector work on an inswing door?
No. The LP-2878 is built for outswing doors only, where the latch and the gap between door and frame are exposed on the outside. On an inswing opening the latch edge faces the secure side, so this plate does nothing for you there. If your door pulls toward you from the outside, this is the right style; if it pushes away, you want an inswing style protector instead.
2) Will the LP-2878 latch guard clear a lever handle or a panic bar?
It works with both levers and exit devices. That is what the slimline profile buys you: at 1-1/2 inches wide the plate covers the latch area without running into the rose of a lever or the end cap and mounting of a rim exit device. On wider guards that clearance is the usual conflict.
3) What size is the Don-Jo LP-2878 latch protector, and will 8-7/8 inches cover my latch?
The plate measures 1-1/2 by 8-7/8 inches. That length centers on the latch and runs well above and below it, which is what stops a pry bar or shim from getting purchase at the latch bolt. The 1-1/2 inch width is the narrow dimension that lets it sit on the door face without fouling adjacent trim.
4) How thick is the steel on the Don-Jo LP-2878 latch guard?
5/16 inch (.3125) steel. That is the whole point of the part: a thin stamped plate deforms under a pry bar and gives the attacker a lip to work with, while material at this thickness resists being peeled back. Substrate is steel, and it is a commercial-duty part rather than a residential one.
5) What finishes does the Don-Jo LP-2878 come in for matching existing door hardware?
Three: DU duronodic brown coated, SL silver coated, and PC prime coated. DU pairs with dark bronze and duronodic aluminum storefront, SL reads with aluminum and satin chrome trim. PC is a primer surface meant to be painted, so pick that one when the door is a painted hollow metal and you want the guard to disappear into it.
6) Do I need a latch guard on an outswing exterior door, or is a deadbolt enough?
A deadbolt and a latch guard solve different attacks. On an outswing door the latch bolt and the door-to-frame gap sit on the unsecured side, so a bar or shim can reach the bolt directly no matter how good the lock is. A plate like the LP-2878 in 5/16 inch steel closes that gap off. It is standard practice on outswing service doors, rear exits, and stair doors in commercial offices, schools, healthcare, retail, warehouses and municipal buildings.
7) What is the difference between a slimline latch protector and a full wrap latch guard?
A slimline plate like the LP-2878 is a flat face-mounted plate, 1-1/2 inches wide, that shields the latch area on the door itself. A wrap-around style bends over the door edge to armor the latch and the lock prep together. Go slimline when there is competing hardware in the way, a lever rose or an exit device end cap, or when the door face has limited room. Go wrap when the lock bore itself needs the protection.
8) How many Don-Jo LP-2878 latch protectors come in a pack?
Shelf packs of 10. If you are standardizing latch guards across a building or a portfolio of units, that quantity covers a run of openings in one line item rather than ten. Property managers doing a floor at a time and contractors stocking a truck both order it this way.
