Kawneer KW450388-17 – Frequently Asked Questions

1) What is the Kawneer KW450388-17 part used for?
The KW450388-17 is a COC blank header and T-bar filler. It closes off and finishes the framing at the top of a door opening, covering the header section and filling the T-bar on a Kawneer Trifab GV450 or GV451 framed entrance. It is a cover and filler piece, not an operating part of the exit device itself.
2) Will the KW450388-17 header filler fit any storefront framing, or only Kawneer Trifab?
Only Kawneer Trifab GV450 and GV451 framing. The KW450388-17 is a system-matched service part cut for those profiles, so it will not align correctly in another manufacturer's storefront system or in a different Kawneer framing series.
3) Does this Kawneer filler work on a 36 inch exit device opening?
Yes, that is exactly what it is sized for. The KW450388-17 is engineered for 36 inch exit device door openings in Trifab GV450/451 framing. A different opening width needs the filler made for that width.
4) What finish does the KW450388-17 come in?
Clear aluminum, which is the standard anodized look on Kawneer storefront and curtainwall profiles. If the surrounding Trifab framing is clear aluminum, the filler will blend with it; a dark bronze or painted storefront will show the difference.
5) Is this a genuine Kawneer part or an aftermarket copy?
It is supplied as an authentic Kawneer service part, so the profile and dimensions match the Trifab GV450/451 system as built. That matters on a repair where the rest of the frame is original Kawneer and the filler has to line up with existing extrusions.
6) Does the KW450388-17 include the exit device or any hardware?
No. It is a single filler and header cover piece for the 36 inch exit device opening. The exit device, trim, and any fasteners or framing components are separate.
7) Is the KW450388-17 suitable for a commercial entrance or is it a residential part?
Commercial only. It is built to commercial standards for high traffic architectural door and framing work, and it shows up on office storefronts, school and healthcare entrances, retail fronts, and municipal buildings running Trifab GV450/451.
8) Can I order this filler as a replacement on an existing building, or is it new construction only?
Either. The KW450388-17 is catalogued as a replacement service part, so it is ordered both for repair and retrofit of an existing Trifab GV450/451 entrance and for new construction where the original filler is needed.
