Kawneer KW450390-17 – Frequently Asked Questions

1) What size door opening is the Kawneer KW450390-17 sized for?
It is cut for a 6-foot door opening, spanning the full opening at the header zone with both blank header and T-bar filler coverage. If your Trifab VG opening is a different width, you need the matching part for that width instead of trimming this one.
2) What does the COC blank header actually do on a Trifab storefront?
It closes out the header above the door opening with an uninterrupted profile, no cylinder or keyed provision in it. Glass front installers use it where a clean blank face is wanted at the head, together with the T-bar filler that finishes the transition into the adjacent framing. If your opening needs a keyed or cylinder provision at the header, this blank version is not what you want.
3) What finish is the Kawneer KW450390-17 supplied in, and will it match my existing storefront?
Clear aluminum. That matches standard clear anodized Trifab VG storefront framing. On a building where the framing was specified in dark bronze or a painted finish, this clear piece will stand out at the header, so a finish-matched part is the better call for those openings.
4) I need to order a replacement header filler for a Trifab VG 450 entrance. What part number do I ask for?
For a 6-foot opening with a blank (non-keyed) header, the Kawneer part is KW450390-17, the COC blank header and T-bar filler. It is ordered as a Kawneer replacement service part, so it is the same component used in the original assembly rather than an aftermarket substitute.
5) Is the KW450390-17 a commercial part or something used on residential entries?
Strictly commercial. It is a Trifab VG storefront and curtainwall component, used on office building storefronts, retail and mall entrances, schools, healthcare entries, government buildings, multi-tenant properties, and industrial entry points. Residential entry doors do not use this framing.
6) Does the KW450390-17 come as one piece or do I get both the header and the T-bar filler?
It covers both functions: the COC blank header and the T-bar filler for the 6-foot opening. Glazing hardware, fasteners, and any door hardware for the opening are separate items and are not part of this filler assembly.
