Cal-Royal CR18-ALUM – Frequently Asked Questions

1) What finishes do Cal-Royal CR18 drop plates come in, and can I match the closer?
Three finishes across all four plate models: aluminum, duronodic, and gold. Every one of the CR18, CR18G, CR18PA, and CR18TJ is orderable in each of the three, so you can match the plate to the CR441 closer body and to the other openings in the building rather than leaving a mismatched bracket on the door face.
2) Does a Cal-Royal CR18 drop plate come with the closer, or do I order the CR441 separately?
The CR18 plates are accessories ordered on their own. Each one is just the mounting bracket for a CR441 Series closer, so the closer, its arm, and its own fasteners are separate line items. Work out your frame condition first, order the matching plate model, and add the CR441 closer alongside it.
3) What is a door closer drop plate actually for, and do I need one at all?
A drop plate is a flat mounting bracket that goes between the closer body and the door or frame when there is not enough surface to screw the closer to directly. If your CR441 closer's mounting holes land fully on the top rail or frame face, you do not need one. You need one when the rail is too shallow, the frame face is too narrow, or a ceiling forces the closer down flush. In the Cal-Royal line those three cases are the CR18, the CR18TJ, and the CR18G respectively, with the CR18PA covering parallel arm mounting on a shallow rail. It is a different item from a closer arm or track, like the Deltana DCHA1050 hold open arm for the DC10 or the LCN 4040SE-3038 standard track, which change how the door behaves rather than where the closer mounts.
4) Is the Cal-Royal CR18 drop plate suitable for a commercial building, or is it a residential part?
It is a commercial part. The CR18 plate family is built for surface mounted door control on commercial openings, the kind of work you see in offices, schools, healthcare, retail, warehouses, multi-tenant residential, and municipal buildings. It is an accessory bracket, not a closer, so it does not carry a closing force of its own, it just puts the CR441 closer where the frame allows it to be mounted.
