Kawneer KW050879-40 – Frequently Asked Questions

1) What exactly is the Kawneer KW050879-40 part, and what does it do on a door closer?
It's a hold open arm assembly, sold as a Kawneer service replacement part for the Norton 1601 door closer series. The arm is what holds the door open at a set position instead of letting the closer pull it shut, so it's the piece you replace when a door stops holding open. It is not a complete closer body, just the arm assembly.
2) Will the KW050879-40 hold open arm fit a Norton 1601 closer I already have on the door?
Yes. The arm is made specifically for the Norton 1601 closer series and is intended to mechanically integrate with it without modification, replacing a worn or damaged hold open arm rather than requiring a whole new closer. If the closer on your door is a different Norton series or another brand, this arm is not the right part.
3) What finish does the Kawneer hold open arm come in, and will it match my existing closer?
Dark Bronze, factory applied. That is the only finish offered for the KW050879-40, so it coordinates with Dark Bronze Norton 1601 closer hardware. On aluminum or clear anodized storefront closers it will read noticeably darker, so for those openings you'd want the arm in the matching finish instead.
4) Do I need to replace the whole Norton 1601 closer if the hold open stopped working?
Not necessarily. If the closer body still cycles and controls the door but the hold open no longer catches, the arm assembly is the usual failure point, and the KW050879-40 replaces it directly so the existing closer stays in service. If the closer body is leaking oil or has lost its closing force, the arm alone won't fix that.
5) Is this hold open arm rated for commercial traffic, or is it a residential part?
Commercial. The KW050879-40 is classified as commercial door hardware and is built for the daily use cycles of commercial openings, with typical use in office buildings, schools, healthcare facilities, retail, government buildings, warehouses, and multi-tenant residential properties.
6) Is the KW050879-40 an OEM part or an aftermarket arm?
OEM. It's an authentic Kawneer service part, carried under model number KW050879-40, so the fit and finish are as furnished by the manufacturer rather than a generic aftermarket substitute.
7) I manage a building with Kawneer storefront doors - can I standardize on this arm across openings?
You can, on any opening running a Norton 1601 closer in Dark Bronze. Ordering the same KW050879-40 arm for those doors keeps hold open behavior and appearance consistent across the building and gives your maintenance crew one part number to stock for that repair.
