Don-Jo DBS-386-PC – Frequently Asked Questions

1) What is the Don-Jo DBS-386 conversion plate used for on a commercial door?
The DBS-386 is a filler and lock adapter plate that covers or adapts an existing cutout or hardware prep in a door. When you pull off old hardware and the prep underneath doesn't match what's going back on, the plate spans the opening so the new hardware mounts against a flat, closed surface instead of a hole. It's an aluminum plate at 1/4 inch gauge, 8 inches by 1-1/4 inches.
2) Will an 8 inch by 1-1/4 inch conversion plate cover the cutout left by my old lock?
Measure the exposed prep first. The DBS-386 covers an area 8 inches by 1-1/4 inches, so it suits a narrow vertical scar, an old strike or edge prep, or a slim mortise cutout. A wide face-bored hole from a cylindrical lockset is broader than 1-1/4 inches and this plate won't close it; for that you want a wider wrap-around or filler plate. The plate has to overlap the opening on all sides to sit flat.
3) Does the Don-Jo DBS-386 come finished, or do I have to paint it?
Two finishes are offered. Prime coated (PC) arrives ready for field painting, which is what you want when the plate has to disappear into a painted door or match a custom color. Duronodic brown coated (DU) is a finished dark bronze and goes on as-is, which suits bronze-toned aluminum storefront and entrance hardware. Order PC only if someone is going to paint it.
4) Is a 1/4 inch gauge aluminum filler plate thick enough to stay flat, or will it oil-can?
At 1/4 inch gauge the plate is stiff enough to bridge an open cutout without flexing or dishing under hardware screws, which is the failure you get with thin sheet fillers over a hole. That thickness stands proud of the door face, so it reads as an applied plate rather than a flush repair. If you need the surface flush with the door, this isn't the part.
5) Should I use a conversion plate or replace the whole door when the new lock doesn't match the old prep?
A conversion plate is the cheap route when the prep is wrong but the door is sound. It adapts or covers the existing cutout so new hardware can mount, no door replacement and no welding or filling. Where it stops working is when the prep is larger than the plate footprint, the door face is damaged around the opening, or the new hardware needs bearing surface that a 1/4 inch aluminum plate at 8 by 1-1/4 inches can't provide. Then you're into a wider wrap-around, a door skin repair, or a new door.
6) Is the Don-Jo DBS-386 rated for commercial traffic or is it a residential part?
Commercial. Don-Jo builds the DBS-386 for commercial door hardware work, and the typical settings are offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings. Aluminum also handles corrosion better than a plated steel filler where the opening sees weather or wash-down.
7) Can I standardize on one filler plate across a building, and does the Don-Jo DBS-386 come in a bulk pack?
It ships in a shelf pack of 10, which is how most maintenance shops and locksmiths stock it, one carton covering a run of openings. For standardizing across a facility, order prime coated and paint to each door's color rather than mixing finishes, or order duronodic brown throughout if the building's hardware is bronze. Same 8 by 1-1/4 inch footprint every time, so the prep coverage is consistent door to door.
8) Will the duronodic brown Don-Jo DBS-386 match my bronze anodized aluminum storefront doors?
Duronodic brown is the dark bronze tone used across aluminum entrance and storefront hardware, so the DU version reads correctly against bronze anodized frames and doors. Exact tone varies between manufacturers and ages with sun exposure, so on a highly visible opening the safer play is the prime coated version painted to match the door in the field.
