Calibre Door Closers CA3010-A – Frequently Asked Questions

1) Will the Calibre A arm work on an aluminum storefront door with a 1 inch top rail?
That's exactly what the Calibre "A" Type End Load top arm assembly is built for: aluminum storefront doors with a 1 inch depth top rail. End loading is what makes it work there, since a side-loading arm needs more room in the rail than a shallow 1 inch section gives you. Model CA3010-A.
2) Do I need to order a left hand and a right hand version of the Calibre CA3010-A arm?
No. The A Type End Load arm is non-handed, so one part covers both left hand and right hand doors. If you are stocking spares for a storefront with doors swinging both ways, a single part number does it.
3) Is this arm for a surface mounted door closer or a concealed one?
Concealed. The Calibre A arm is a top arm for overhead concealed closers, specifically Calibre OHC units in center hung applications. If you have a surface mounted closer on the face of the door or frame, this is not the arm for it.
4) My storefront door is offset pivot hung, not center hung. Is the Calibre A arm still the right part?
No. This end load arm is specified for center hung configurations. On an offset pivot door the arm geometry and closer are different, so you would need the arm matched to that hanging arrangement rather than the CA3010-A.
5) Can I replace just the closer arm instead of the whole overhead concealed closer?
Yes, when the closer body itself is still good. The Calibre A arm is sold as a standalone arm assembly, so a bent or worn top arm on a Calibre overhead concealed closer can be swapped without pulling the closer out of the header. It is a common storefront repair after a door gets forced past its stop.
6) What is the difference between an end load and a side load closer arm?
It is how the arm enters the door's top rail. An end load arm slides in from the end of the rail, which is what lets it work on a shallow 1 inch deep top rail where a side-loading arm will not fit. Side load arms drop in from the face side and need a deeper rail section. Measure the top rail depth on your storefront door before choosing; at 1 inch, the A Type end load is the one that goes in.
7) Will this arm fit doors from another closer manufacturer?
The A Type arm is specified for Calibre overhead concealed closers. Match the arm to the closer brand and model already in your header. Storefront OHC arms are not interchangeable across manufacturers as a rule, so identify the closer first.
8) Is this arm suitable for a high traffic commercial entrance?
It is built for commercial use, precision machined for durable performance in commercial settings, and is the standard top arm on Calibre overhead concealed closers in aluminum storefront entrances. For a facility standardizing spare parts across a run of storefront doors, one non-handed part number covers every opening with a 1 inch top rail.
