Kawneer KW450440-40 – Frequently Asked Questions

1) What does the Kawneer KW450440-40 shear block package actually do?
Shear blocks are the structural connectors that tie framing members together in a Kawneer storefront. The KW450440-40 is the center hung version, supplied as a complete package to provide the structural support a center hung door opening needs so the door pivots and operates correctly within the framing. It is a genuine Kawneer service replacement part, not an aftermarket equivalent.
2) Which Kawneer framing systems does the KW450440-40 fit?
It is made for Kawneer Trifab 400 and Trifab 450 Series framing systems in a center hung door configuration. If your storefront is a different Kawneer system, or the door is offset pivot rather than center hung, this is not the correct package.
3) What finish does the KW450440-40 come in, and will it match my existing Kawneer frames?
Dark Bronze, which is one of Kawneer's standard architectural finishes and coordinates with matching Trifab framing components. If your building's frames were specified in clear anodized or another finish, the visible portions will not match.
4) Is the KW450440-40 sold as a kit or as a single block?
It ships as a complete shear block package rather than a loose individual block, which is how Kawneer supplies it for service and replacement work. One package is ordered under model number KW450440-40.
5) I'm repairing an existing Kawneer entrance. Is this an original equipment part or an aftermarket copy?
Original. The KW450440-40 is an authentic Kawneer service replacement component, manufactured to the same standards as the parts originally installed in Trifab 400 and 450 framing, so it maintains the system's structural and operational integrity without modification.
6) Is the KW450440-40 suitable for residential storefront work?
It's a commercial-grade part. Kawneer classifies it for commercial applications, and Trifab 400 and 450 framing is used in office entrances, schools, healthcare, retail storefronts and municipal buildings rather than residential openings.
