Kawneer KW050821-40 – Frequently Asked Questions

1) What door height does the Kawneer KW050821-40 continuous geared hinge cover?
The KW050821-40 is sized for door heights up to 7' to 8'. It runs the full length of the door edge, so the hinge length is matched to the leaf height rather than to a set of individual butt hinge locations. If your Kawneer leaf is shorter than 7 feet, this is the wrong length part and you want the shorter continuous hinge for that height range.
2) Is the Kawneer KW050821-40 a genuine Kawneer part or an aftermarket hinge?
It is a genuine Kawneer service replacement part, listed under Kawneer Service Parts. For Kawneer aluminum entrance doors that matters, because the hinge has to match the factory door and frame prep on the Kawneer leaf. An aftermarket continuous hinge of nominally the same length may not line up with that prep.
3) I am replacing a sagging hinge on a Kawneer entrance door. Is this the right repair part?
Yes, if the leaf falls in the 7 to 8 foot height range and the existing hinge is a Kawneer continuous geared hinge. It is supplied as a direct replacement component for compatible Kawneer door assemblies, so you are restoring the opening to its original hinge rather than re-prepping the door edge and frame for a different hinge type.
4) What finish is the KW050821-40 hinge, and will it match my other Kawneer storefront doors?
Dark Bronze, factory applied, and it is intended to coordinate with Kawneer architectural aluminum door and framing systems. If the rest of your entrance is Kawneer dark bronze, this hinge will read the same. On a clear anodized or painted white opening it will not match, so order the finish that matches the leaf you are working on.
5) Why use a continuous geared hinge instead of three butt hinges on an aluminum entrance door?
A continuous geared hinge carries the door along its whole height, so the load is spread down the edge instead of being concentrated at two or three hinge points. On high traffic aluminum entrances that is the difference between a door that stays in alignment and one that sags and starts dragging the threshold. Butt hinges are fine on lower traffic openings, but once a door is cycled constantly, full-length support is the reason spec writers call for geared hinges.
6) Is the KW050821-40 hinge rated for commercial use or is it a residential part?
Commercial. It is classified as a commercial product and built for high-traffic commercial door applications, the kind of service you see in offices, schools, healthcare facilities, retail, and government buildings.
7) Does the KW050821-40 come in more than one size or finish?
No. It is a single part: the 7 to 8 foot door height continuous geared hinge in Dark Bronze. Other heights and finishes are separate Kawneer part numbers, so confirm the leaf height and the existing finish before you order.
