Don-Jo BLP-107-630 – Frequently Asked Questions

1) Will the Don-Jo BLP-107 latch protector work on an in-swing door?
No. The BLP-107 is an out-swing latch guard, so it mounts on the exterior face of a door that swings away from you and covers the gap where the latch is exposed to a pry bar or shim. On an in-swing door the latch is on the protected side and this plate has nothing to cover; you need an in-swing style guard (a wrap that shields the strike side of the frame) instead.
2) Does the BLP-107 fit a key-in-lever lockset, or only knobs?
Lever locks. The BLP-107 is cut for key-in-lever trim and works with both Grade 1 and Grade 2 levers, which covers most commercial lock lines. If the opening has a knob or a mortise lock with an escutcheon, this is not the right plate profile for it.
3) What size is the Don-Jo BLP-107 latch guard, and will it cover the latch area on a standard commercial door?
The BLP-107 measures 3-1/4 x 7 inches, which spans the latch area of a key-in-lever lockset on a commercial out-swing door. Before ordering, check that your stile has 3-1/4 inches of flat face beside the lock edge; a narrow-stile aluminum door often does not, and a narrower latch guard is the right call there.
4) How thick is the steel on the Don-Jo BLP-107, and is it heavy enough for a back door that keeps getting pried?
12 gauge, .104 inch stainless steel. That is a structural-weight plate, not a decorative wrap, and it is the thickness you want on a rear service door, a stockroom, or any exterior opening where someone has already worked the latch with a bar. Thinner guards in the 18 to 22 gauge range dent and peel; this one resists the pry.
5) What finish does the Don-Jo BLP-107 come in, and will it hold up outdoors?
One finish: 630, satin stainless steel. Because it is stainless rather than plated steel, it holds up on exterior openings and in coastal or wash-down environments where a plated finish would rust at the fastener holes. 630 also matches the satin stainless trim on most commercial lock lines, so it blends with existing hardware on a fleet of doors.
6) I'm standardizing latch guards across a building. Is the BLP-107 one plate that covers all my lever doors?
It covers the out-swing lever openings. Every door where a key-in-lever lock swings out takes the same 3-1/4 x 7 inch BLP-107 in 630 finish, which keeps one part number on the shelf and one look across the building. Your in-swing doors and any knob or mortise openings will need a different guard, so walk the building and count swings before you set the order quantity.
7) What else can I use if the Don-Jo BLP-107 does not fit my opening?
Trimco's PG8000 Series panic and latch guards are the other line to look at. They cover both panic-device and latch-guard applications, so if the opening has an exit device rather than a key-in-lever lock, or you need a profile the BLP-107's 3-1/4 x 7 inch plate will not sit on, that series is where to shop.
8) Will a latch protector like the Don-Jo BLP-107 stop someone from shimming or loiding my latch?
That is what it is built for. On an out-swing door the latch and the gap between door and frame sit on the attack side, and a 12-gauge stainless plate spanning the latch area blocks the bar, the shim, and the card. What it does not fix is a worn strike or a lock with a short throw, so if the door already rattles loose in the frame, sort the strike and the lock before you count on the guard.
9) Is the Don-Jo BLP-107 a commercial-duty latch protector or a residential one?
Commercial. It is specified for office buildings, schools, healthcare, retail, warehouses, multi-tenant residential, and government facilities, and the 12-gauge stainless build is sized for that traffic and that threat level. It will install fine on a residential exterior door, but you are buying commercial-grade steel to do it.
10) How is the BLP-107 packed if I'm buying for multiple job sites?
It ships in a shelf pack of 10, which suits a contractor or distributor retrofitting a run of doors rather than a single opening. For a one-door repair you are still buying into that pack quantity.

Designed for Levers: It's specifically designed to work with key-in-lever locks, accommodating up to a 3-3/4" escutcheon or rose.
