Don-Jo 504-FE Wrap Around Mortise Lock Door Reinforcement Plate, 12" x 1" for 1-3/4" Doors

The Don-Jo 504-FE Wrap Around is a heavy-duty mortise lock door reinforcement plate engineered to protect the door edge at the mortise lock prep against forced-entry attacks. Designed for 1-3/4" commercial doors with an 86 cut-out, this wrap-around plate covers both faces of the door edge to distribute kick and pry loads across a wider surface area. Measuring 12" H x 1" W and formed from 22-gauge (.032") steel, the 504-FE installs cleanly over existing mortise latch preps without modification. Available in Oil Rubbed Bronze (10B/613) and Satin Stainless (S/630) finishes to coordinate with existing door hardware.

  • Forced-Entry Protection: Wraps both faces of the door edge at the 86 cut-out to distribute kick and pry loads across a wider surface area, reinforcing the most vulnerable point of a mortise lock installation.
  • Heavy-Gauge Steel Construction: Formed from 22-gauge (.032") steel for durable, long-lasting reinforcement in demanding commercial environments.
  • Mortise Lock Compatibility: Specifically designed for the 86 cut-out mortise latch prep, installing cleanly over existing preps without modification.
  • Multiple Finish Options: Available in Oil Rubbed Bronze (10B/613) and Satin Stainless (S/630) to coordinate with existing door hardware and architectural finishes.

Don-Jo 504-S-FE – Frequently Asked Questions

1) Will the Don-Jo 504-FE wrap around fit a 1-3/8 inch door?
No. The 504-FE is formed for 1-3/4 inch doors, which is the standard commercial thickness, and the wrap will not close down on a thinner 1-3/8 inch door. Older interior and residential doors are commonly 1-3/8 inch, so measure the door edge before ordering. If yours is 1-3/8 inch you need a wrap around sized for that thickness instead, not this one.
2) Can I use the 504-FE wrap around on a door with a cylindrical lockset?
Not a match. The 504-FE is made for the 86 mortise cut-out, a long rectangular pocket in the door edge. A cylindrical or bored lockset uses a much smaller latch faceplate in the edge and a round bore through the face, so the 504-FE opening will not line up with anything on that door. For a bored lock you want an edge or face wrap made for that prep.
3) What finishes does the Don-Jo 504-FE mortise wrap around come in, and will they match my existing door hardware?
Two finishes, and no others: Oil Rubbed Bronze, ordered as 10B and equivalent to BHMA 613, and Satin Stainless, ordered as S and equivalent to BHMA 630. If your building is standardized on 630 satin stainless, which most commercial openings are, take the S. Dark bronze levers and mortise trim pair with the 10B. There is no brass or painted option on the 504-FE, so if your openings are 605 or 606 brass the plate will read as a contrast rather than a match.
4) How thick is the steel on the Don-Jo 504-FE, and is it heavy enough for a high traffic tenant entry?
The plate is 22-gauge steel, .032 inch thick, formed to wrap the door edge. The security comes from the geometry more than the raw thickness: wrapping around onto both faces ties the two sides of the door together at the weakest point, the mortise pocket, so a kick or a pry bar loads the whole 12 inch plate instead of just the lock faceplate screws. It is built for commercial duty and is a common fix on office, school, healthcare, retail, and multi-tenant entry doors.
5) What do I have to specify when ordering a Don-Jo 504-FE wrap around?
Finish only. The 504-FE is a single size, 12 inches by 1 inch for a 1-3/4 inch door with an 86 mortise cut-out, so there is no size, hand, or backset to call out. Pick 10B oil rubbed bronze or S satin stainless and that is the order. There is no left hand or right hand version to get wrong.
6) I manage a building with dozens of mortise lock doors. Can I standardize on one wrap around plate for all of them?
Across any 1-3/4 inch door with an 86 mortise prep, yes, one part covers the whole set. The 504-FE has no handing and no size variations to track, so the only thing to keep consistent building-wide is the finish, 10B oil rubbed bronze or S satin stainless. Openings that are a different thickness, or that carry bored cylindrical locks rather than mortise locks, fall outside it and need a different plate.
7) Do I need to modify the door or take the mortise lock apart to install a 504-FE?
No door modification. The 504-FE slips over the door edge and sits on the existing mortise prep, so nothing gets drilled, routed, or enlarged. You will pull the lock faceplate to seat the wrap over the cut-out and put it back, but the door itself is untouched. That is the reason it works as a retrofit on an in-service opening rather than a shop job.
8) Can the Don-Jo 504-FE be used on apartment entry doors?
It works on any apartment or multi-tenant entry door that is 1-3/4 inch thick with an 86 mortise lock prep, and that is a common combination in commercial-grade multi-family construction. The plate is built for commercial duty, so it is not undersized for a residential corridor door. Lightweight interior residential doors at 1-3/8 inch, or units with bored knob locks, are outside what it fits.
