Kawneer KW400549-29 – Frequently Asked Questions

1) What does the Kawneer KW400549-29 part actually consist of?
KW400549-29 is a self-aligning (S/A) offset arm shear block package butt hinge for the Kawneer Trifab 400 framing system. It comes as a package, meaning the shear block components ship with the hinge so a service replacement can be done in one order rather than sourcing the block separately. Finish is black.
2) Will the KW400549-29 hinge work on a Kawneer framing system other than Trifab 400?
No. It is engineered exclusively for the Trifab 400 framing system and is meant to fit that system's architecture without modification. If your storefront or curtain wall is a different Kawneer series, order the hinge specified for that series instead, since the shear block geometry is what ties this part to Trifab 400.
3) I'm replacing a hinge on an existing Trifab 400 door - is this a direct swap?
Yes, for Trifab 400. As the OEM replacement component it drops into the existing system without modification, and because the shear block comes in the package you are not matching up a separate block from the original build. Take the part number off the hinge or the framing schedule to confirm you are on Trifab 400 and not an adjacent Kawneer series.
4) Is this a genuine Kawneer part or an aftermarket equivalent?
It is a genuine Kawneer service part, OEM-sourced, listed under Kawneer Service Parts. For glass front installers and property managers maintaining an existing Trifab 400 entrance, that matters: the part is built to the original equipment standard so the door hangs and aligns the way the system was engineered to.
5) Is the KW400549-29 hinge rated for commercial entrance traffic or is it a light-duty part?
Commercial. The hinge is classified for commercial door applications, not residential, and is intended for entrance use in offices, retail storefronts, schools, healthcare and institutional buildings, and multi-tenant properties.
6) Can I order the KW400549-29 hinge in a finish other than black?
Black is the finish this part ships in, factory applied. There is one configuration of KW400549-29, so if your existing Trifab 400 entrance is clear or bronze anodized you will want to confirm the hinge is concealed or acceptable visually before ordering, or specify the Kawneer service part for your finish.
7) What does the self-aligning offset arm design do for installation?
The offset arm, self-aligning configuration takes the guesswork out of setting the door in the opening. Instead of shimming and re-checking to get the leaf plumb, the arm geometry brings the hinge into alignment as it is fastened, which is why Kawneer uses it as the service replacement on Trifab 400 doors. Useful when you are swapping a hinge on a door that has to go back into an existing frame the same day.
