Kawneer KW035128 – Frequently Asked Questions

1) What does the Kawneer KW035128 AR header bolt actually do in a 3-point lock?
The KW035128 is the header bolt, the top latching point in a Kawneer 3-point locking assembly. It throws up into the frame head to hold the top of the door, working alongside the lock's other engagement points. If a door with a Kawneer 3-point lock latches at the sill and center but no longer catches at the top, the header bolt is the part being replaced.
2) Will the KW035128 header bolt work on a door taller than 7 feet?
No. The AR header bolt is specified for Kawneer 3-point lock systems on doors up to 7 feet in height. On a taller opening you need the header bolt sized for that door height, not this one. Measure the leaf before ordering; a door over 7 feet takes a different service part.
3) Which Kawneer KW035128 model do I order, 4085-01 or 4085-04?
The AR header bolt comes as two ordering choices, model 4085-01 and model 4085-04. Match the number stamped on or listed for the bolt you are pulling out of the existing Kawneer 3-point lock, since the two are not interchangeable options on the same assembly.
4) Is the KW035128 a genuine Kawneer part or an aftermarket copy?
It is a genuine Kawneer service part, built to the original manufacturer's specification for the 3-point lock assembly. That matters on aluminum storefront work, where an off-spec bolt often will not line up with the existing header strike prep.
5) Can I use this header bolt on a residential entry door?
It is a commercial-only part. The AR header bolt is intended for commercial door applications running Kawneer 3-point locking systems, the kind found on aluminum entrances in offices, schools, healthcare and municipal buildings. It is not a fit for a residential wood or fiberglass entry door.
6) I manage a building with Kawneer entrances. Can I stock this bolt as a standard repair item?
Yes, if your openings run Kawneer 3-point locks on leaves up to 7 feet. It is a drop-in replacement part for that assembly, so keeping the correct model (4085-01 or 4085-04) on the shelf lets a tech restore top-point latching without pulling the whole lock. Confirm which of the two models your doors use before you standardize.
7) Does the KW035128 come with the rest of the 3-point lock or is it just the bolt?
Just the header bolt. The KW035128 is a single service component of the 3-point lock, not the complete locking assembly. If the center lock body or the bottom bolt is also worn, those are separate Kawneer parts.
