Kawneer KW035103 – Frequently Asked Questions

1) Will the Kawneer KW035103 latch lock fit my Kawneer storefront door?
The KW035103 AR4510 latch lock is built for pre-1989 Kawneer door systems in the Entara, Tuffline, and 350/500 Series families. It has a 1-1/2 inch backset and is configured left-handed for outswing doors, so it drops into the original door edge prep without additional boring. If your door is a newer Kawneer system, or swings in, or hands right, this is not the part.
2) How do I know if I need the left-hand or right-hand version of the AR4510 latch lock?
Handing is fixed on the KW035103 - it ships left-handed for an outswing door and is not field reversible. Stand outside the door, on the side it swings toward you: if the hinges are on your left, you need the left-hand outswing part. Get it backwards and the latch bolt bevel faces the wrong way and will not latch into the strike.
3) Does a 1-1/2 inch backset latch lock need a different door prep than a standard 2-3/8 or 2-3/4 inch backset lock?
Yes. The 1-1/2 inch backset on this AR4510 latch is an aluminum storefront dimension, much shorter than the 2-3/8 and 2-3/4 inch backsets used on bored locks in wood and hollow metal doors. It is sized for the narrow stile of a Kawneer aluminum door, so it goes into the existing Kawneer edge prep with no modification and will not swap into a conventional door.
4) My Kawneer door swings inward. Can I still use the KW035103?
No. The KW035103 is configured specifically for outswing doors, matching the original latch geometry and throw direction of outswing pre-1989 Kawneer assemblies. An inswing opening needs the inswing version of the AR4510 latch lock instead.
5) Is the KW035103 a genuine Kawneer part or an aftermarket copy?
It is a genuine Kawneer service part, model KW035103, made to the original AR4510 latch lock specification. That matters on legacy openings where the latch geometry and throw direction have to match the existing strike and door prep exactly.
6) Is this latch lock suitable for a high-traffic commercial entrance?
The KW035103 is a commercial-rated part, built to the standard of the Entara, Tuffline, and 350/500 Series entrance doors it services. It is the correct choice for office building, school, healthcare, retail storefront, and municipal entrance maintenance where the original Kawneer latch lock has worn out.
