Von Duprin KR9954-7FT-28 – Frequently Asked Questions

1) How do you get a full-width opening through a pair of doors with a Von Duprin KR9954 mullion?
The KR9954 is a key removable mullion, so the center post comes out with a key. Day to day it stands between the two leaves and gives both exit devices something to latch into. When you need to move a bed, a pallet, or gym equipment through the opening, an authorized person unlocks it, lifts the mullion out, and the whole double door width is clear. Put it back in and the opening is a latched pair again. That is the difference between a removable mullion and a fixed one, which stays put permanently and permanently costs you the center of the opening.
2) Which KR9954 height do I order for an 8 foot opening?
Two heights are made: 7 foot 5 inch and 8 foot 5 inch. Measure the frame opening height, not the door leaf, and take the mullion that spans it. An 8 foot opening needs the 8 foot 5 inch mullion, which comes blank so the strike locations get laid out to match where your devices actually sit. Both heights are fire rated and both are finished 689/US28 aluminum painted.
3) Can the KR9954 removable mullion be used on a fire rated pair of doors?
Both KR9954 configurations, the 7 foot 5 inch and the 8 foot 5 inch blank, are fire rated. That is what lets a removable mullion be used on a fire rated pair at all, since an unrated post would break the rating of the assembly. Keying it removable also means the mullion can come out for moving equipment and go back in without the opening losing its rated center post.
4) What does the BLANK on the 8 foot 5 inch KR9954 mullion mean?
Blank means no strike cutouts. The 8 foot 5 inch mullion ships without the strike prep so the holes can be laid out in the field to suit where the exit devices land on a taller opening. You still use two 499F or two 268 strikes, they just get located on site. If you want the prep done at the factory, the 7 foot 5 inch version is the one that comes prepped.
5) Removable mullion or rim exit devices without a mullion, which do I need for a double door?
A pair of doors with rim exit devices needs something for the latches to catch. The mullion is that something. Without a center post you are into surface or concealed vertical rod devices, which latch at the head and the sill of each leaf instead and cost you rod maintenance over time. A key removable mullion like the KR9954 lets you run simpler rim devices on both leaves and still open the full width when a key comes out to pull the post. Where the opening never needs to be fully clear, a fixed mullion does the same job without the removable mechanism.
6) Is the Von Duprin KR9954 mullion steel or aluminum?
Steel. The mullion is built on a steel substrate, which is what carries the load when someone leans on a rim device latched into the center of a busy opening. The 689/US28 finish is aluminum painted, so the color reads aluminum, but the post underneath is steel.
7) What finish does the KR9954 mullion come in and will it match my other Von Duprin hardware?
One finish only: 689/US28, aluminum painted. Both heights carry it. 689 is the standard aluminum painted spec across commercial exit hardware, so it lines up with devices and trim ordered in 689 on the rest of the openings. If the building is standardized on a plated finish, the mullion will not match it, since no other finish is made for this model.
