Kawneer KW200799-29 – Frequently Asked Questions

1) What does the KW200799-29 actually seal against?
It's the weather sweep that seats in the bottom rail of the door, sealing the gap between the rail and the threshold against air, dust, and draft infiltration. It is not a threshold, not a door shoe for a glass stile, and not part of the latching hardware. If your complaint is light and wind under a Kawneer aluminum door, this is the piece that fixes it.
2) Is the KW200799-29 a genuine Kawneer part or an aftermarket sweep?
Genuine Kawneer service part, model KW200799-29, supplied as an OEM replacement component. That matters on Kawneer entrances because the sweep has to seat correctly in the specific bottom rail profile; a generic sweep often will not retain in the rail kerf.
3) Can I order just the sweep, or do I have to replace the whole bottom rail?
Just the sweep. KW200799-29 is catalogued as a replacement part, so it is sold on its own for maintenance swaps where the rail and the exit device are still serviceable. Property managers routinely change only the sweep on a door that has started leaking air while everything else on the leaf is fine.
4) Does the KW200799-29 work on a door with a panic exit device?
Yes, it is designated an exit device part and is intended to work alongside compatible exit device bottom rail assemblies. The sweep lives in the bottom rail and does not interfere with rim device or vertical rod hardware above it. On a surface vertical rod setup, confirm the bottom rod and latch location while fitting the sweep so the two do not foul each other.
5) I'm standardizing sweeps across a building with pairs of Kawneer doors. Can one part number cover all the leaves?
For any leaf up to 48 inches wide, yes. Because KW200799-29 is a variable-size sweep sized to the opening up to 48 inches, a single part number covers a mix of leaf widths across an estate, including both leaves of a pair. Order one per leaf, not one per opening.
6) What finish does the Kawneer bottom rail sweep come in, and will it look right on a dark storefront?
Black is the finish, and it is the only one offered on KW200799-29. It reads as a neutral dark line at the bottom rail, so it disappears on dark bronze and black anodized Kawneer entrances. On a clear anodized or white painted door the sweep will still be visible as a black strip at the bottom.
7) Is this sweep rated for commercial traffic or is it a light-duty residential weatherstrip?
Commercial. The KW200799-29 is specified for commercial door applications, the kind of high-cycle openings found in offices, schools, healthcare, retail, warehouses, multi-tenant residential, and municipal buildings. It is not a residential weatherstrip product.
