Kawneer KW400548-40 – Frequently Asked Questions

1) What exactly is the Kawneer KW400548-40 and what does it do on a door?
It's a single-action offset arm shear block package with offset pivot, supplied as a Kawneer service replacement part for the Trifab 400 system. The shear block anchors into the framing and the offset arm/pivot geometry sets the door's swing axis off the door edge, so the leaf pivots on an offset centerline rather than on butt hinges. It ships as a package, so the pivot and shear block components come together rather than being sourced separately.
2) Will the KW400548-40 offset pivot package work on a Kawneer framing system other than Trifab 400?
No. Kawneer engineers this shear block package specifically for the Trifab 400 system, and the shear block and arm geometry are matched to that framing. If your storefront or curtain wall is a different Kawneer series, you need the service part called out for that system instead. Confirm the framing series stamped or documented on the opening before ordering.
3) Is this a single-action or double-acting pivot package?
Single-action (S/A) only, meaning the door swings one direction. It will not support a double-acting leaf that swings both ways. If the opening is a two-way swing door, this package is the wrong part.
4) What finish is the Kawneer KW400548-40 supplied in, and will it match my existing Trifab 400 storefront?
It comes in Dark Bronze, factory applied, which is a standard Kawneer coordinating finish for Trifab 400 framing and hardware. If your existing entrance is Dark Bronze the part will blend with the surrounding frame and pivot hardware. On a clear anodized or painted-to-color system, the exposed portion of the pivot will read as a different color.
5) Is this an aftermarket pivot or a genuine Kawneer part?
Genuine Kawneer, sourced through the manufacturer's service parts program rather than a look-alike. For property managers and facility teams maintaining installed Trifab 400 entrances, that matters because the shear block has to seat in the original framing pocket and the arm has to reproduce the factory pivot geometry.
6) Does the offset arm shear block package include everything needed, or do I have to order the pivot separately?
The package covers the shear block components and the offset pivot together, so the pivot and arm function is supplied as one assembly rather than pieced together. Fasteners and framing repairs beyond the package, plus any top pivot or closer arm work the opening needs, are separate.
7) Is the KW400548-40 handed?
Offset pivot arms carry a swing direction, and this is a single-action assembly, so the door's hand and swing determine which arm you need. Note the existing leaf's hand and swing off the opening before ordering, and order the matching Kawneer service part number for that condition.
8) Is the KW400548-40 suitable for a high traffic commercial entrance?
Yes. It's a commercial-rated component, built to Kawneer's commercial standards for demanding door applications, and it's routinely used servicing office buildings, schools, healthcare entrances, retail storefronts and municipal buildings. It is not a residential pivot set.
