Kawneer KW133587-40 – Frequently Asked Questions

1) What is a removable mullion and why would I need one with a Kawneer 1786 rim exit device?
A rim exit device latches into a strike, not into the opposite door, so on a pair of doors it needs something to latch against. That is what the Kawneer KW133587-40 removable mullion assembly does: it stands in the middle of the paired opening and carries the strike for the 1786 rim device. It pulls out when you need the full clear width of the opening for moving equipment or oversized loads, then drops back in. If you were considering a surface vertical rod device instead, that route latches at the head and the sill and leaves the center clear permanently, no mullion involved.
2) Will the KW133587-40 mullion work on a pair of doors taller than 8 feet?
No. The KW133587-40 is built for openings up to 8 feet in door height. Anything taller needs a longer mullion assembly, so measure the opening from the threshold to the head before ordering.
3) Does this Kawneer mullion work with exit devices other than the 1786?
It is engineered specifically for the Kawneer 1786 rim exit device, and the strike arrangement is built around that device. If your pair of doors carries a different rim device, match the mullion to that device's own prep rather than assuming this one lines up.
4) Is the KW133587-40 a genuine Kawneer part or an aftermarket copy?
It is a genuine Kawneer service part, made to OEM specification, and it is catalogued under Kawneer service parts as a replacement component. For a property manager maintaining an existing Kawneer storefront entrance, that matters: the hole pattern and the strike geometry match what is already in the opening.
5) What finish does the Kawneer KW133587-40 mullion come in, and will it match my storefront?
Dark Bronze, factory applied. That is the same finish family used across Kawneer commercial aluminum door and framing systems, so it reads consistently against dark bronze anodized storefront. If your entrance is clear anodized or a painted color, this one will not blend and you want the mullion in the matching finish instead. Dark Bronze is the only finish offered on the KW133587-40.
6) I only need the mullion bar for a Kawneer double door repair. Is this a complete assembly?
The KW133587-40 is sold as a mullion assembly, model KW133587-40, not a loose bar. It is the service part you order when the existing removable mullion on a Kawneer 1786 pair is damaged, missing, or you are adding mullion service to an existing rim device pair.
7) Is this mullion rated for a commercial high-traffic entrance or is it light duty?
Commercial. The mullion assembly is built for high-traffic commercial environments, and it is used in offices, schools, healthcare, retail storefront, government buildings, warehouses and multi-tenant properties running Kawneer door systems. It is not a residential part.
