Kawneer KW037888-40 – Frequently Asked Questions

1) What frame reveal does the extra-length Kawneer KW037888-40 arm cover?
It is built for frames with reveals from 5 to 7-1/2 inches. That is the whole reason for the extra length: on a deep reveal a standard arm cannot reach the soffit bracket at the right geometry, and the closer either binds or loses closing force near the latch. If your reveal is under 5 inches, this is the wrong arm.
2) Does the Kawneer KW037888-40 arm hold the door open?
No. This is a no hold open regular arm, so the door closes every time it is released. That is what you want on rated openings and on any door that has to stay latched; if you need a door that parks open, a hold open arm is a different part and this one will not do it.
3) Can I buy just the arm, or do I have to replace the whole Norton 1600 closer?
Just the arm. The KW037888-40 is sold as a replacement part, so a bent or sprung arm on an otherwise sound Norton 1600 closer body is an arm swap, not a closer swap. The closer body, mounting screws and soffit plate stay in place.
4) What finish is the KW037888-40 closer arm, and will it match my storefront hardware?
Dark Bronze, factory applied. It is the common anodized-look finish on Kawneer aluminum entrances, so it coordinates with dark bronze storefront framing and pulls. If the rest of the opening is aluminum or clear anodized, the bronze arm will read as a mismatch on the pull side where it is visible.
5) Is the Kawneer KW037888-40 a genuine part or an aftermarket arm?
It is a genuine Kawneer service part, made to the original dimensional spec for the assembly. For a property manager standardizing closers across a building, that matters more than it sounds: an off-spec arm changes the geometry and you end up chasing closing speed and latch problems door by door.
6) Is this arm rated for commercial traffic or is it a light duty part?
Commercial. The KW037888-40 is specified for commercial door hardware service work, typical on office building entrances, retail storefronts, schools, healthcare and municipal buildings where the closer runs all day.
