Kawneer KW133586-40 – Frequently Asked Questions

1) What door height does the Kawneer KW133586-40 removable mullion fit?
The KW133586-40 mullion assembly is cut for an 82-7/16 inch door height. Mullion length is not adjustable on a service part like this, so if your pair of doors is a different leaf height, this is the wrong part number and you need the Kawneer mullion dimensioned for your opening.
2) Does this Kawneer mullion work with any rim exit device, or only the 1786?
It is built for the Kawneer 1786 Rim Exit Device. The mullion carries the strike arrangement that device latches into, so pairing it with a different manufacturer's rim device is not something Kawneer specifies here. If your doors run 1786 rim devices on both leaves, the KW133586-40 is the matching removable mullion.
3) Why would I use a removable mullion instead of surface vertical rod devices on a pair of doors?
A removable mullion lets both leaves run simple rim exit devices, which latch into the mullion rather than into the head and threshold. That keeps hardware off the door faces and out of the floor, where vertical rods and bottom latches collect dirt and fall out of adjustment. The trade-off is the mullion sits in the middle of the opening; when you need the full clear width for moving equipment or furniture, you pull the mullion out. That removability is the whole point of the KW133586-40.
4) What finish does the KW133586-40 mullion come in, and will it match my other Kawneer entrance hardware?
Dark Bronze, applied at the factory, which is one of the standard Kawneer architectural finishes used across storefront and entrance systems. If the existing doors and frames in the opening are Dark Bronze Kawneer, this drops in without a visual break down the middle of the pair. For clear anodized or other finish openings, order the mullion in that finish instead.
5) I am replacing a damaged mullion on an existing Kawneer pair. What do I need to confirm before ordering the KW133586-40?
Two things settle it: the leaf height must be 82-7/16 inches, and the exit devices on the doors must be Kawneer 1786 rim devices. Get those right and this is a direct service-part replacement for the mullion in that opening. Finish is Dark Bronze, so also check that against the existing frame before you pull the old one out.
6) Is the Kawneer KW133586-40 a genuine Kawneer part or an aftermarket equivalent?
It is a genuine Kawneer service part, sold under Kawneer's own model number KW133586-40. For a property manager or facilities group maintaining Kawneer entrances, that matters because the mullion has to sit correctly in the Kawneer frame and receive the 1786 device strikes without field modification.
7) Is this mullion suitable for a commercial entrance, or is it a light-duty residential part?
Commercial only. The KW133586-40 is a commercial-grade assembly intended for paired-door openings in offices, schools, healthcare corridors, retail storefronts, government buildings, warehouses, and multi-tenant common areas, which is exactly the traffic a removable mullion sees.
