Kawneer KW400548-17 – Frequently Asked Questions

1) What does the Kawneer KW400548-17 shear block package actually do on a Trifab 400 door?
The KW400548-17 is the single-acting offset arm shear block package with offset pivot for the Trifab 400 system. The shear block carries the structural load transfer at the pivot point of the offset arm assembly, so the door hangs and swings on the correct pivot geometry. It ships as a complete package for installation into an existing Trifab 400 offset pivot assembly.
2) Will the KW400548-17 work on a double-acting door?
No. It is a single-acting (S/A) configuration, built for doors that swing one direction only. On a double-acting opening the pivot geometry is different and this package is the wrong part.
3) Is this Kawneer offset pivot shear block compatible with framing systems other than Trifab 400?
It is matched specifically to the Trifab 400 offset pivot system. Kawneer service parts are system-specific, so if your framing is another Kawneer series, this is not the package to order for it. Confirm the frame is Trifab 400 before ordering.
4) Is the KW400548-17 a genuine Kawneer part or an aftermarket copy?
Genuine Kawneer service part, listed under Kawneer Service Parts, supplied as the OEM replacement component for Trifab 400 door systems. That matters on architectural framing because the shear block has to seat in the factory pocket without modification.
5) I only know the number stamped on the old part. What do I order to replace a Trifab 400 offset arm shear block?
Order Kawneer part KW400548-17. That is the model designation for the single-acting offset arm shear block package with offset pivot on Trifab 400. It is sold as one package rather than loose pieces, so there are no separate options to specify beyond the part number.
6) What finish does the Kawneer KW400548-17 come in?
Clear Aluminum, factory applied. That is the standard match for Trifab 400 storefront and curtain wall framing, so a repaired opening keeps a consistent look next to the untouched doors. Only the one finish is offered on this part number.
7) Is this part rated for commercial storefront traffic or is it a light-duty residential item?
Commercial. It is built to Kawneer's commercial-grade standards and intended for storefront and curtain wall entrances, office and retail entries, schools, healthcare, and government buildings. There is no residential version of this shear block package.
