Don-Jo CR-125 – Frequently Asked Questions

1) What is a Don-Jo CR-125 closer reinforcement plate actually for?
The CR-125 is a steel plate that goes in a hollow metal or lightweight door to give a door closer something solid to screw into. Hollow doors don't have enough material at the closer location to hold screws under the repeated pull of a closer arm, so the plate spreads that load across 12 inches of 10-gauge (.134) steel. It is not a closer and it is not a cover plate, it is the backing the closer mounts to.
2) Will a 1-3/4 inch wide reinforcement plate fit inside my door's top rail?
The CR-125 measures 12 inches by 1-3/4 inches, so it needs a clear 12 inch run of top rail and 1-3/4 inches of height inside the door at the closer location. On a standard commercial hollow metal door that fits the top rail without trouble. Measure the interior rail depth on a narrow-rail or glass-stile aluminum door before ordering, since 1-3/4 inches is more than some narrow stiles give you.
3) Is 10-gauge steel heavy enough for a closer on a high traffic entry door?
10-gauge is .134 inch thick steel, which is heavier than the face sheet of most hollow metal doors, so the plate rather than the door skin is carrying the closer screws. Don-Jo builds the CR-125 for commercial service, and it is the grade of backing used on office, school, healthcare, retail, warehouse, and municipal openings where the closer cycles all day.
4) Do I need a closer reinforcement plate, or a wrap around plate?
Two different jobs. A closer reinforcement like the CR-125 is installed inside the door to create the mounting substrate for a door closer. A wrap around plate goes on the outside of the door and covers or repairs a damaged lock area. If your problem is that closer screws are stripping out or the closer is pulling loose from a hollow door, the reinforcement is what you want.
5) Does the Don-Jo CR-125 come with mounting screws or a template for the closer?
The CR-125 is the steel reinforcement plate itself, 12 x 1-3/4 inches in 10-gauge. Drilling and tapping for the specific closer you are mounting is done to that closer's own template, and the closer's fasteners come with the closer. Order the closer and its mounting hardware separately.
6) Can I buy one Don-Jo CR-125 or do they come in a box quantity?
The CR-125 is packaged as a shelf pack of 10. That suits a contractor doing a run of openings or a facility keeping spares on the shelf rather than someone repairing a single door.
7) Can I add a closer reinforcement to a door that is already hung, or does it have to go in before?
A reinforcement like the CR-125 is an internal plate, so it wants to be installed with access to the inside of the door at the closer location, which normally means during fabrication or with the door off and the top cap or rail opened. If the door is already hung and closed up, plan the work around getting access rather than assuming a surface install, because this plate is a backing plate, not a face-applied one.
8) Will the CR-125 work for both regular arm and parallel arm closer mounting?
The plate gives you a 12 inch by 1-3/4 inch field of 10-gauge steel to fasten into, and it is not drilled for any one closer pattern. Position it so the closer body or the parallel arm shoe footprint falls within that 12 inch run, and either mounting style has solid metal behind the screws.
