Kawneer KW035666-40 – Frequently Asked Questions

1) Will the KW035666-40 fit my Kawneer 4040-18TJ transom?
Yes, that's exactly the configuration it is specified for. Kawneer lists the KW035666-40 as the hold open transom part for 4040XP-3071 systems in the 4040-18TJ setup. If your door carries a different Kawneer closer or transom designation, this is not the part number to order.
2) Is the KW035666-40 a genuine Kawneer part or an aftermarket copy?
Genuine Kawneer service part, sold under Kawneer's own model number KW035666-40. That matters on Kawneer storefront and entrance systems, where the components are dimensioned to the manufacturer's own extrusions and a generic substitute won't line up.
3) What finish does the KW035666-40 come in, and will it match my other Kawneer hardware?
Dark Bronze only, which is one of the standard Kawneer architectural finishes. It will blend with existing Dark Bronze 4040XP hardware on the same entrance. If your storefront is clear anodized or black, the visible appearance will not match.
4) I'm a property manager with several Kawneer storefront doors. Can I stock this one part number for all of them?
Only for the openings that use the 4040XP-3071 with a 4040-18TJ transom and are finished in Dark Bronze. Kawneer entrances vary by closer series and transom configuration from door to door, so walk the openings and note the series stamped on each closer before standardizing on KW035666-40.
5) Is the KW035666-40 a complete door closer or just a component?
It's a replacement component, not a closer assembly. Kawneer classifies it as a service replacement part providing the hold open transom function within an existing 4040XP installation, so the rest of the operator and transom hardware needs to already be in place and serviceable.
6) Is this Kawneer hold open part suitable for a high traffic commercial entrance?
It's built and classified for commercial use, not residential. Kawneer service parts of this type go into office buildings, schools, healthcare facilities, municipal buildings and retail storefronts running 4040XP entrances, which is the duty level the part is made for.
