Kawneer KW400548-29 – Frequently Asked Questions

1) What is the Kawneer KW400548-29 offset arm shear block package used for?
It's the offset pivot hardware for Kawneer Trifab 400 door assemblies. The shear block package carries the offset arm so the door swings on the correct pivot geometry, which is what keeps the door aligned and the exit device operating the way it was set up originally. It is sold as a genuine Kawneer service replacement part, so it goes back into the opening in place of the original pivot hardware.
2) Will the KW400548-29 shear block fit a Kawneer framing system other than Trifab 400?
No. This shear block package is engineered specifically for the Trifab 400 system and is a direct-fit replacement there. Kawneer builds its framing families with different shear block and pivot geometry, so if your storefront or curtain wall is another Kawneer series, order the service part called out for that series instead.
3) My Trifab 400 door is sagging and the exit device isn't latching cleanly. Is the shear block the part I need?
Often, yes. On a Trifab 400 the offset arm shear block sets the pivot geometry; when it wears or shifts, the door drops out of alignment and the exit device latch stops meeting the strike properly. Replacing it with the KW400548-29 package restores the original pivot geometry so the door hangs true again. Check the closer and the threshold pivot at the same time before you condemn the shear block.
4) Is this a single-action or double-action pivot part?
Single action. The KW400548-29 is a single-action offset arm shear block package, so it suits a door that swings one direction only. A double-acting opening needs different pivot hardware.
5) Do I have to modify the door or frame to install the KW400548-29?
No modification is called for. Kawneer supplies it as a direct-fit service replacement for Trifab 400 door assemblies, so it drops into the existing pivot prep when you are replacing worn original hardware.
6) Does the KW400548-29 come in a finish that matches dark bronze or black Kawneer doors?
It's supplied in Black, which lines up with black Trifab 400 door hardware. If your frames are clear anodized or dark bronze, ask for the Kawneer service part in the matching finish rather than fitting this one, since the pivot arm is visible at the top and bottom of the door.
7) Can I use this on a residential entry door?
No. This is commercial hardware, made for aluminum Trifab 400 storefront and entrance assemblies in offices, schools, healthcare, retail and government buildings. It isn't a residential hinge or pivot replacement.
