Pro-Lok - Wrap Plate, 2-1/8″ Bore – 5″ x 14″ x 1-3/4″

That is exactly the prep it's cut for. The Pro-Lok wrap plate is bored 2-1/8 inches with a 2-3/4 inch backset, and it wraps a 1-3/4 inch thick door. If your opening is an older 1-3/8 inch door, or the lock sits on a 2-3/8 inch backset, this plate won't line up with the existing holes.

That's the job this part does. The Pro-Lok wrap around plate is stainless steel and folds over the door edge to repair, reinforce and protect a wood or metal door where forced entry has split or deformed the lock area. It covers 5 by 14 inches of face, so it spans damage above and below the bore rather than just ringing the hole. If the stile is broken through or the door is delaminated, a plate won't bring it back, but a kicked lock area with the bore still intact is what this is for.

Both. The plate is compatible with key-in-knob locksets and with deadbolts, since the 2-1/8 inch bore and 2-3/4 inch backset are the same prep either one uses. On a door with a knob and a separate deadbolt, check the center-to-center spacing of your two holes against the 14 inch plate before you order.

Two preps. Standard bore prep puts the 2-1/8 inch hole at a 2-3/4 inch backset in the usual position, and the centered version places a single hole in the middle of the 14 inch plate for one latch or one lock. Pick centered when you're covering a single deadbolt and want the damage spread evenly above and below it; pick standard when you're going back over an existing knob or lock prep.

Depends which side failed. A wrap plate like this Pro-Lok goes on the door itself, wrapping the edge and both faces around the lock bore, and it's what you use when the door split at the knob or deadbolt. If the frame gave way and the strike tore out of the jamb, a plate on the door fixes nothing, you need a strike reinforcement in the frame. Plenty of kick-ins damage both, and in that case you install one of each.

Rated for residential, commercial and industrial use, and the 1-3/4 inch door thickness it's built for is the standard commercial door. For a property manager standardizing across units, one stainless plate with a 2-1/8 inch bore and 2-3/4 inch backset covers the common apartment entry prep, so the same part number repeats door to door.

Yes, it's made for wood or metal doors. The plate wraps the edge and clamps over both faces rather than relying on the door core, so a hollow metal door works as long as it's 1-3/4 inches thick and prepped for a 2-1/8 inch bore. On metal you'll be drilling and tapping or using self-tappers through the skin rather than driving wood screws.

Stainless steel is the finish sold on the 5 x 14 plate. Pro-Lok makes this wrap plate in duronodic as well, so if you're matching dark bronze hardware on the rest of the building, that's the one to ask for. On a fleet of units where the existing knobs and deadbolts are chrome or brushed, the stainless plate reads closest.
