Don-Jo EF-86 – Frequently Asked Questions

1) What does a Don-Jo EF-86 edge filler actually do on a door?
The EF-86 is a steel plate that covers a mortise lock cutout left in the edge of a door, so the exposed pocket is filled and the door edge is protected. It's the fix when a mortise lock comes out and a cylindrical lock or nothing at all goes back in, leaving a raw cutout in the edge. It's a cover plate for the edge, not a lock and not a wrap around for the door face.
2) Will the Don-Jo EF-86 cover my mortise lock cutout, and what size is it?
The EF-86 measures 8 inches by 1-1/4 inches, so it covers a mortise pocket up to that footprint on the door edge. Measure your cutout first: anything longer than 8 inches or wider than 1-1/4 inches will still show. Standard commercial mortise lock bodies are cut roughly 8 inches tall in the edge, which is what this size targets.
3) Do I need an edge filler or a wrap around plate for my door?
Different problems. An edge filler like the EF-86 covers the mortise pocket in the EDGE of the door, 8 inches by 1-1/4 inches. A wrap around plate covers damage or an old bore on the FACE of the door around the lock. If your old mortise lock left a hole in the edge and a scarred face, you may need both: the filler for the edge and a face plate or wrap for the flat.
4) How heavy is the steel on the Don-Jo EF-86 edge filler?
7-gauge, .180 inch thick steel. That's a stiff plate, not a thin shim, so it holds flat across an 8 inch opening in the door edge instead of oil-canning where the lock pocket used to be. For a school corridor or a hospital door that takes daily abuse, that thickness is the point of the part.
5) What finishes does the Don-Jo EF-86 mortise edge filler come in?
Four: prime coated (PC), brass plated (BP), chrome plated (CP), and Duronodic brown coated (DU). Prime coated is the one to order when the door gets painted, since it takes finish paint directly and disappears into the door edge. Chrome plated reads closest to a satin or bright chrome lockset, brass plated to brass trim, and Duronodic to dark bronze hardware.
6) I'm buying one edge filler for one door - does the EF-86 come as a single?
The EF-86 is packed as a shelf pack of 10. If you're doing one door, you're still buying the pack of 10, which is why it's usually stocked by locksmiths and maintenance shops running a fleet of openings rather than bought for a single repair. Property managers standardizing across a building typically go through them.
7) Is the Don-Jo EF-86 filler plate right for a commercial door or is it a residential part?
Commercial. The 7-gauge steel and the 8 inch length are sized to commercial mortise lock preps, which is what you find in office buildings, schools, healthcare, retail and government facilities. Residential interior doors are typically bored for cylindrical locks and won't have a mortise pocket in the edge for it to fill.
8) Can I paint the Don-Jo EF-86 to match my door?
Order the prime coated version (PC). It ships with a primer over the steel so it accepts finish paint and blends into a painted door edge. The plated and coated options (brass, chrome, Duronodic brown) are finished surfaces meant to be left as they are and matched to existing hardware.
