Kawneer KW450440-29 – Frequently Asked Questions

1) Will the Kawneer KW450440-29 shear block package work with Trifab 451 or other Kawneer framing systems?
The KW450440-29 center hung shear block package is made for Kawneer Trifab 400 and 450 Series framing only. It is a genuine Kawneer service part cut to those系 profiles, so it should not be substituted into other Kawneer framing families. If your framing is a different Trifab series, order the shear block package called out for that series instead.
2) Is this Kawneer shear block package for center hung doors or offset pivot doors?
Center hung. The KW450440-29 is configured for center hung pivot door applications in Trifab 400 and 450 framing, where the pivot sits on the door centerline. An offset pivot opening uses different reinforcement and this package is not the part for it.
3) Is the KW450440-29 a direct replacement, or does the frame need modification?
It is sold as a drop-in replacement for existing Trifab 400 and 450 installations, so a glazier servicing an existing center hung entrance replaces like for like rather than reworking the framing. It is a replacement service part, not a field-fabricated assembly.
4) What exactly do I order to get this shear block, and is it a single piece or a kit?
Order Kawneer model KW450440-29. It ships as a package, not a loose single block, so it covers the center hung shear block components for one Trifab 400 or 450 application. There are no finish or size options to specify.
5) What finish does the KW450440-29 come in, and will it show once installed?
It comes in Black, and only Black. Since the shear block package is concealed reinforcement at the framing joint on a center hung Trifab 400 or 450 opening, the finish matters mainly for matching dark anodized framing at any point it is visible at the head or sill.
6) Is the Kawneer KW450440-29 suitable for residential storefront work?
No. This is a commercial-only service part, intended for Kawneer Trifab 400 and 450 storefront and curtain wall entrances in offices, schools, healthcare, retail, and government buildings. Residential doors do not use this framing.
