Kawneer KW450390-29 – Frequently Asked Questions

1) Will this part work on an 8-foot or 7-foot Trifab VG door opening?
No. The KW450390-29 is cut and configured for a 6-foot door opening in Trifab VG 450/451. A wider or taller opening takes the corresponding Kawneer service part for that opening size, so measure the existing opening before you order this one.
2) What does a COC blank header and T-bar filler actually do in a storefront opening?
It closes out the head of the door opening. The blank header spans the top of the opening and the T-bar filler fills the transition where the horizontal meets the framing, so you get a finished, continuous look above the door instead of an open or mismatched joint. It is a framing close-out component, not a latch, closer, or operating hardware.
3) What finish does the Kawneer KW450390-29 header filler come in?
Black, applied at the factory to match other Trifab VG 450/451 components finished in black. It is supplied in that one finish, so if the surrounding framing on your job is clear or bronze anodized, this part will not match.
4) Is this a genuine Kawneer part or an aftermarket copy?
It is a genuine Kawneer service part, model KW450390-29, catalogued under Kawneer Service Parts. For glass front installers and property managers maintaining an existing Trifab VG storefront, that matters: the extrusion profile and finish are made to the original system dimensions rather than approximated.
5) Can I use the KW450390-29 on a residential entry door?
No. This is a commercial-grade component for Kawneer Trifab VG aluminum storefront and curtain wall framing. Residential entries do not use that framing system, so there is nothing for the header and T-bar filler to fit into.
