Kawneer KW450390-40 – Frequently Asked Questions

1) What framing system does the Kawneer KW450390-40 blank header and T-bar filler fit?
The KW450390-40 is a Kawneer service part built for Trifab VG 450 and 451 series aluminum framing, sized for a 6 foot door opening. It is not a universal storefront filler, so if your frame is a different Kawneer series or a different opening width, this part won't line up in the header zone.
2) What does the COC blank header actually do on a storefront door opening?
The blank header covers the head of the opening with no cylinder or keyed cutout in it. Pick it when nothing needs to penetrate the header face. If your opening takes a closer, a concealed overhead device, or a cylinder at the head, a blank header is the wrong piece because there is no prep in it.
3) What finish does the Kawneer KW450390-40 header filler come in?
Dark Bronze, and that is the only finish it ships in. For a glass front installer matching an existing Trifab VG run, Dark Bronze is the common architectural anodized tone on these systems, so it will blend with the surrounding framing, but if your storefront is clear anodized or a painted color the part will read as a mismatch at the header.
4) Is the KW450390-40 an aftermarket copy or a genuine Kawneer part?
It is a genuine Kawneer service part, model KW450390-40. For a property manager or GC repairing an installed Trifab VG 450/451 entrance, that matters because the extrusion profile and finish are the manufacturer's own, so it seats in the original framing without shimming or field modification.
5) Do I need anything else with the KW450390-40 to close out the header?
What you get is the blank header plus T-bar filler for the 6 foot opening. The T-bar filler bridges the header zone so the framing closes and aligns; fasteners and sealant are a job-site item, not part of the extrusion. If your opening is a pair or a different width, order the header sized to that opening instead of cutting this one down.
6) Is this Kawneer header filler suitable for residential storefront work?
It is a commercial-duty part. Trifab VG 450/451 is commercial aluminum framing used on office entrances, schools, healthcare, retail storefronts, and municipal buildings, and the KW450390-40 is intended for those environments rather than residential door frames.
