Kawneer KW200799-40 – Frequently Asked Questions

1) What is the Kawneer KW200799-40 and where does it go on the door?
It's a bottom rail weathering sweep, a genuine Kawneer service part that seals the gap along the bottom rail of a commercial door. It cuts air infiltration, dust, and light moisture at the threshold. It is a replacement component, so you can restore weather sealing on an existing Kawneer door without swapping the whole assembly.
2) Can I use this sweep on a hollow metal or wood door?
No. This is a Kawneer service part built to fit the bottom rail of Kawneer aluminum entrance doors and their exit device assemblies. For a hollow metal or wood door you want a standard surface-applied door sweep or shoe sized to that door, not a rail-specific Kawneer part.
3) Is the Kawneer bottom sweep dark bronze the same color as the rest of my storefront hardware?
The KW200799-40 carries a factory-applied Dark Bronze finish, which is the standard dark bronze Kawneer uses across its aluminum entrance hardware, so it reads consistently against dark bronze rails and frames. If your openings are clear anodized or black, order the sweep in that finish instead rather than mixing.
4) Do I have to replace the whole exit device to fix a leaking bottom rail?
No. The KW200799-40 is sold as a standalone service part specifically so maintenance crews can restore the weather seal on an existing Kawneer installation without pulling the exit device or the door. For a facility standardizing across many openings, ordering the sweep alone keeps the repair to a single component.
5) What part number do I give my Kawneer supplier for the dark bronze bottom sweep?
Model KW200799-40, Kawneer's bottom rail weathering sweep in Dark Bronze, variable size up to 48 inches. That single number covers the full width range, so you specify the finish and the width you need at order time.
6) Is this a commercial-duty part or a residential weatherstrip?
Commercial. Kawneer builds the KW200799-40 for commercial entrance traffic, which is why it shows up in office buildings, schools, healthcare, retail, warehouses, and municipal facilities. It isn't a residential-grade foam or vinyl sweep.
