Pro-Lok ELP-100 7″ Interlocking Latch Protector

No. The ELP-100 is built for out-opening (out-swinging) doors, where the latch and the gap between door and frame are exposed on the outside. On an in-swinging door the latch edge isn't accessible from outside, so a latch guard of this style has nothing to cover. For an inward-swinging opening you want an interior-mount latch protector instead, not this one.

The ELP-100 measures 7 x 5/8 inches in steel. That's a tall, narrow guard: it runs the length of the latch area on the strike side rather than covering a wide plate area. If you need a wider footprint over the latch, the Don-Jo LP-307 is 2-5/8 by 7 inches and the Don-Jo NELP-207 is 3-1/2 by 6.5 inches.

An interlocking guard wraps the door-to-frame joint so the two halves engage each other. That resists spreading attacks, where someone jacks the door away from the frame to pop the latch clear of the strike. A plain flat guard only blocks a shim or pry tool reaching the latch. The ELP-100 does both: it obstructs access to the latch and resists tampering by spreading devices.

Both. The ELP-100 works with deadbolts as well as lock sets, so it covers a single-cylinder deadbolt on an out-swinging service door or a cylindrical lockset latch. On openings with a deadbolt above a lockset, measure the vertical span you need covered against the guard's 7 inch length.

The Don-Jo LP-307 is a latch protector for aluminum storefront entrance doors, 2-5/8 inch by 7 inch in 12-gauge steel, built for out-swing openings. It matches the ELP-100 on the 7 inch dimension, and the ELP-100 is likewise made for out-opening doors and works with deadbolts and lock sets across residential, commercial, and industrial doors.

For an opening with a panic device, the Trimco PG8000 Series covers panic guards as well as latch guards. The Pro-Lok ELP-100 is a 7 inch interlocking latch protector that blocks access at the latch and resists devices used to spread the door from the frame on out-opening doors, so it addresses the latch rather than the full width of an exit device.

No. The Don-Jo GLP-307, LP-307, and NELP-207 are all specified for out-swing openings, and the Pro-Lok ELP-100 is likewise made for out-opening doors. None of them is the part for a door that swings toward the attack side.

Both mount on out-swinging doors, but they're shaped for different problems. The ELP-100 is a narrow 7 x 5/8 inch interlocking guard that engages the door and frame to resist spreading. The Don-Jo LP-307 is a 2-5/8 by 7 inch 12-gauge steel plate made specifically for aluminum storefront entrance doors, and the GLP-307 covers the same 2-5/8 by 7 inch footprint for aluminum entrance doors. If your problem is a pry bar spreading the opening, the interlocking design addresses it; if it's a shim or tool reaching a storefront latch, the wider Don-Jo plate covers more of the gap.

Not quite. The ELP-100 is matched to deadbolts and lock sets. A door with a rim exit device needs a panic guard sized to cover the rim latch and strike, which is a different profile. The Trimco PG8000 Series covers panic and latch guards for that application.

That's the job it's built for. On an out-swing door the latch bolt and the door/frame gap face outward, which is where loiding and shimming attacks come from. The ELP-100's steel body blocks access to that gap, and because it interlocks with the frame it also fights the pry-and-spread method that defeats a plain cover plate. It's a retrofit part: it goes over the existing latch or deadbolt rather than replacing it.

Both are 2-5/8 inch by 7 inch out-swing latch protectors for aluminum entrance doors. The LP-307 is specified for aluminum storefront entrance doors in 12-gauge steel; the GLP-307 is specified for aluminum entrance doors. Both carry an entrance function, as does the application the Pro-Lok ELP-100 covers on out-opening doors.

The Pro-Lok ELP-100 is offered in Aluminum, Chrome, and Duro finishes, so a single 7 inch protector can be matched to different door hardware across a set of buildings. The Don-Jo LP-307 is specified in 12-gauge steel at 2-5/8 inch by 7 inch, and the Trimco PG8000 Series spans both panic guards and latch guards.

Three: Aluminum, Chrome, and Duro. Aluminum and Chrome are the usual picks for matching aluminum storefront and stainless or chrome trim; Duro is the darker option when you don't want the guard reading bright against a painted or dark frame.

Yes to both. The ELP-100 is rated for residential, commercial and industrial use, and Pro-Lok classes it as commercial door hardware. Property managers standardizing exterior out-swing doors across a portfolio can spec the same 7 inch guard on every opening and just pick one finish to keep it uniform.
