Don-Jo CR275 – Frequently Asked Questions

1) What does a Don-Jo CR-275 closer reinforcement plate actually do on a door?
The CR-275 is a steel backing plate that goes under a surface door closer so the closer's mounting screws pull against 12-gauge (.104) steel instead of the door skin alone. It spreads the closer's load over a 14 inch by 4-1/8 inch area, which is what keeps screws from pulling through and the door face from dimpling after a few thousand cycles. It is not the closer and not a bracket, just the reinforcement behind it.
2) Is the CR-275 reinforcement plate big enough to cover my closer's mounting holes?
It measures 14 x 4-1/8 inches, sized for standard commercial surface closer shoe and body mounting patterns on the door face. Lay your closer's paper template over that footprint before you drill. If your closer body pattern runs longer than 14 inches, or the mounting holes sit outside a 4-1/8 inch band, you need a larger plate.
3) Will a closer reinforcement plate help on a hollow metal door where the closer screws keep stripping?
That is the exact failure the CR-275 is built for. On a hollow metal or wood door with no internal reinforcement at the closer location, screws bite only the face and work loose. Adding the 12-gauge steel plate gives the fasteners real material to hold and distributes the closing forces across the plate rather than a few screw holes. It is a common fix in schools, healthcare corridors, and multi-tenant residential buildings where doors get heavy traffic.
4) Is the Don-Jo CR-275 rated for commercial use or is it a residential part?
Commercial. Don-Jo classifies the CR-275 as a commercial door hardware item, and the 12-gauge (.104) steel body is heavier than anything you would need behind a residential closer. Typical placements are office buildings, retail, industrial and warehouse facilities, and government buildings.
5) Do I have to buy the CR-275 in a multi-pack?
Don-Jo packages the CR-275 in a shelf pack of 10. That suits a contractor or facility manager doing a run of openings, or a distributor holding stock, more than someone repairing a single door.
6) Is there more than one version of the Don-Jo CR-275 to choose from?
No. The CR-275 is a single model with one size and one steel construction, so there is no handing, finish, or length decision to make on the order. You specify the model and that is the whole spec.
