Kawneer KW400549-17 – Frequently Asked Questions

1) What system does the Kawneer KW400549-17 shear block butt hinge package fit?
The KW400549-17 is a Kawneer service part built for the Trifab 400 framing and door system. It's a self-applying (S/A) offset arm shear block butt hinge package, so the offset arm geometry and shear block are matched to Trifab 400 profiles rather than to a generic aluminum door. If your opening is a different Kawneer platform, this is not the part for it.
2) Does the KW400549-17 include the shear block, or do I have to order that separately?
It ships as a complete shear block package, so the shear block that carries the load at the hinge point comes with the hinge rather than being a separate line item. One part number covers the assembly.
3) Is the KW400549-17 a genuine Kawneer part or an aftermarket copy?
It's a genuine Kawneer service part, ordered by Kawneer's own number KW400549-17. That matters on a Trifab 400 opening because the hinge has to pick up the existing shear block prep in the frame; an aftermarket substitute may not land on the same points.
4) What finish does the Kawneer KW400549-17 hinge package come in?
Clear Aluminum only. That's the standard clear anodized look that matches most Trifab 400 storefront framing. If your building's framing is dark bronze or black anodized, the hardware will not match visually.
5) What does "self-applying" mean on this Kawneer offset arm hinge?
Self-applying (S/A) means the hinge and shear block locate themselves to the framing during assembly, so the hinge position repeats without separate layout work. For a glass front installer swapping a hinge on an existing Trifab 400 door, that keeps the door hanging at the same alignment it had before.
6) Do I need one KW400549-17 package per door or per hinge point?
The KW400549-17 is a single offset arm shear block butt hinge package, so it covers one hinge location. A door hung on multiple butt hinge points needs a package for each one. It is sold as a replacement service part, which is how it's usually bought, one at a time to repair a failed hinge.
7) Is this hinge package rated for commercial traffic or is it a light-duty residential part?
Commercial. The KW400549-17 is specified for commercial aluminum door work, the kind of thing you see on office entrances, school and healthcare glazed doors, retail storefronts, and multi-tenant lobbies. It is not a residential hinge.
