Kawneer KW091331-29 – Frequently Asked Questions

1) What door system does the Kawneer KW091331-29 bottom rail lock fit?
The KW091331-29 bottom rail lock is built for the Kawneer 1040 Sliding Door system only. It is an OEM Kawneer service part, so it drops into the 1040 bottom rail as a direct replacement. If your opening is a different Kawneer series, this is not the part, and swapping it into a non-1040 rail is not something the part is made for.
2) Is the KW091331-29 a genuine Kawneer part or an aftermarket copy?
Genuine Kawneer. The KW091331-29 is catalogued as a Kawneer service part made to Kawneer's OEM specifications for the 1040 Sliding Door, not a generic equivalent. For a property manager or facilities crew keeping a fleet of 1040 doors running, that matters: the fit and function match the factory component the door was built with.
3) Is this bottom rail lock rated for commercial traffic or is it a residential part?
Commercial. The KW091331-29 is classed as commercial-grade hardware and is used on storefront, office, healthcare, education, government and warehouse 1040 sliding door installations. It is a service part for high-traffic entrances rather than a residential patio door lock.
4) What does the bottom rail lock actually do on a Kawneer 1040 sliding door?
It secures the door panel at the base. The lock sits in the bottom rail and provides the locking engagement at the bottom of the sliding panel, which also supports proper door alignment. When a 1040 door is loose at the bottom or will not secure at the sill, this is the component being replaced.
5) What finish does the Kawneer 1040 bottom rail lock come in?
Black, applied at the factory. It is a single-finish part, so there is no anodized clear or bronze option to pick on the order. If the rest of your 1040 hardware is black, this matches; if your doors are a different finish, the lock body will still function but it will read as black at the bottom rail.
6) Do I need to order anything else with the KW091331-29 to finish the repair?
The KW091331-29 is sold as a single replacement component for the 1040 bottom rail. It is one SKU in one configuration, so there are no handing, size or finish options to specify. Any sill strike, keeper or cylinder already in the opening stays in place unless it is damaged, in which case those are separate Kawneer service parts.
