Don-Jo CP-258-PC – Frequently Asked Questions

1) What is a Don-Jo CP-258 cylinder plate actually used for?
The CP-258 is a 2-5/8 inch round steel plate that covers a cylinder hole in a commercial door. When a lock or deadbolt gets removed, downsized, or swapped for something with a smaller cylinder, you're left with an open bore in the face of the door. The plate covers it so the door reads finished instead of drilled. It is not a lock, a lock part, or a reinforcement for a working cylinder, it is trim over the hole.
2) I removed a deadbolt from a commercial door and there's a hole left. Do I need a wrap-around plate or just a cylinder plate?
If the only damage is the round cylinder bore itself and the door face around it is sound, a round cylinder plate like the CP-258 is the simpler fix, it covers the 2-1/8 inch bore with its 2-5/8 inch face and nothing more. Go to a wrap-around instead when the edge of the door is torn up, the latch prep is damaged, or you need to cover a bore and a latch prep together, since a wrap folds over the door edge and a flat round plate does not.
3) What finishes does the Don-Jo CP-258 cylinder plate come in?
Five: brass plated, chrome plated, duronodic brown coated, silver coated, and prime coated. If you're patching a hole on a door you're about to repaint, take the prime coated version, it ships with a factory primer and takes paint directly, so you can match the door instead of trying to match a plated finish to aging hardware. Brass or chrome plated make more sense when the door stays as-is and the plate has to blend with the existing lock and hinges.
4) Is 16 gauge steel heavy enough for a cylinder plate on a high-traffic commercial door?
16 gauge (.060) steel is the working weight for this kind of trim, and it's what the CP-258 is made from. It holds its shape against carts, keys, and shoulder traffic in a corridor or a stairwell rather than dishing in like thin sheet trim. The plate is rated by Don-Jo for commercial use, not residential-only duty.
5) How many cylinder plates come in a pack of Don-Jo CP-258?
They ship in shelf packs of 10. That's worth knowing before you order for a single door, because you'll end up with nine spares. For a locksmith van or a maintenance shop turning over locks across a building, ten is about right for one standardization pass.
6) Can the Don-Jo CP-258 be painted to match a door?
The prime coated version is made for exactly that. The primer is factory applied as a paint-ready surface, so you scuff it, shoot your topcoat, and it matches the door or frame color. The plated and coated versions (brass, chrome, silver, duronodic brown) are finished goods and are meant to be installed as-is.
