Kawneer KW091331-40 – Frequently Asked Questions

1) Will the Kawneer KW091331-40 bottom rail lock fit any Kawneer sliding door, or only the 1040?
Only the 1040. The KW091331-40 is a Kawneer service replacement bottom rail lock made specifically for the Kawneer 1040 Sliding Door system, and it installs in an existing 1040 assembly without modification. If your opening is a different Kawneer sliding or swing series, this is not the part for it.
2) I'm a property manager replacing a broken lock on a Kawneer 1040 slider. Do I need to replace the whole door rail?
No. The bottom rail lock is sold on its own as a drop-in service replacement, so a failed lock can be swapped out of an existing 1040 sliding door assembly without changing the rail or the door leaf. That keeps the entrance out of service for a repair, not a rebuild.
3) Is the KW091331-40 a genuine Kawneer part or an aftermarket copy?
It is a genuine Kawneer service part, not an aftermarket equivalent. That matters on a storefront repair where the rail prep and the lock body have to line up exactly with what the factory installed.
4) What finish is the Kawneer KW091331-40 bottom rail lock, and will it match my existing dark bronze storefront doors?
Dark Bronze, applied at the factory, so it matches the standard Kawneer Dark Bronze used across 1040 door assemblies. If the rest of your entrance is clear anodized or another Kawneer finish, order the matching finish version of the bottom rail lock instead.
5) Is this bottom rail lock suitable for a high traffic commercial entrance?
Yes. The KW091331-40 is a commercial-rated component, built for the same duty as the original hardware in Kawneer 1040 entrances, and it is used in office buildings, retail storefronts, healthcare and school entryways, and government and multi-tenant properties.
