Kawneer KW037891-40 – Frequently Asked Questions

1) Will the Kawneer KW037891-40 arm work with a Norton 1600 Series closer?
Yes. The KW037891-40 is a regular arm hold open extra-length arm built specifically for Norton 1600 Series door closers, sold as a genuine Kawneer service replacement part. It is not a universal arm, so pair it with a 1600 Series closer body rather than another Norton family.
2) What frame sizes does this extra-length hold open arm cover?
The KW037891-40 is sized for frames from 5 to 7-1/2. That is the whole reason for the extra-length arm: on a deeper reveal, a standard regular arm cannot reach the door with correct geometry. If your frame falls outside that 5 to 7-1/2 range, this is the wrong arm.
3) What does a regular arm hold open do compared with a plain regular arm?
A hold open arm lets the door stop and stay at a set open position instead of closing every time, which is what you want for loading, moving carts, or keeping a corridor open during peak traffic. A plain regular arm always returns the door to closed. Note that a hold open arm is a mechanical hold, so it is not appropriate on an opening required to self-close.
4) I am replacing a broken closer arm, not the whole closer. Is this just the arm?
Correct, the KW037891-40 is the arm assembly only, catalogued as a replacement service part. The Norton 1600 closer body, shoe mounting screws already in the frame, and any drop plate stay in place. Order the closer separately if the body itself is failing.
5) Is the KW037891-40 arm suitable for a commercial building, or is it a light-duty residential part?
It is a commercial part. Kawneer lists it for commercial use and it is the service part specified for Norton 1600 closers in offices, schools, healthcare, retail, warehouses, multi-tenant residential buildings, and government facilities.
6) What finish is the Kawneer KW037891-40 hold open arm?
Dark Bronze. That is the only finish this arm is supplied in, so if your existing closer and frame are aluminum or painted another color you will have a visible mismatch at the arm.
