Von Duprin 5654 7FT 2IN US28 – Frequently Asked Questions

1) Will a Von Duprin 5654 mullion work on a pair of doors with rim exit devices?
That is exactly what it is for. The 5654 is a removable aluminum center post for a pair of doors, and it comes factory prepped to accept two 299 strikes, one for the device on each leaf. Rim exit devices need a strike to latch into, and on a pair with no fixed center post the mullion is what carries that strike. Order it prepped as supplied and you are not field-drilling strike locations.
2) What lengths does the Von Duprin 5654 aluminum mullion come in?
Three lengths: 7 ft 2 in, 8 ft 2 in, and 10 ft 2 in. Pick the one that covers your frame opening height, since the mullion runs floor to head. A standard 7 ft opening takes the 7 ft 2 in; the taller two are for 8 ft and 10 ft openings, which is where you land in warehouse, industrial, and some institutional frames. Each length is offered in all four finishes.
3) Do I need a mullion, or should I use vertical rod exit devices on my pair of doors?
Both approaches secure a pair. A mullion like the 5654 lets you run a rim device on each leaf, latching into the 299 strikes prepped into the post, which keeps the hardware on the door simple and puts the latching at one point per leaf. Vertical rod devices skip the center post entirely and latch top and bottom, which is what you want when the opening has to stay clear for wide loads or carts. The tradeoff with the mullion is that someone has to remove it to get a full clear opening; the tradeoff with vertical rods is more hardware and rods on each door.
4) What finishes are available on the Von Duprin 5654 mullion?
Four: 313/710 dark bronze anodized aluminum, 612/US10 satin bronze clear coated, 628/US28 satin aluminum clear anodized, and 606/US4 satin brass. 628 satin aluminum is the usual match for aluminum storefront and clear-anodized frames; 313 dark bronze pairs with bronze anodized entrances. All four are offered in each of the three lengths, so finish does not restrict your height choice.
5) Does the Von Duprin 5654 mullion come with the strikes, or do I order those separately?
The mullion is prepped for two 299 strikes, which means the holes and mounting prep are cut at the factory. Prep is not the same as supply, so plan your order around the strikes and the exit devices as separate line items and confirm your rim devices are the ones that take a 299 strike. The prep is fixed at two strike positions, so it suits a pair where both leaves carry a rim device.
6) I manage a building with several double-door entries. Can I standardize on one mullion across all of them?
Only where the opening heights match. The 5654 is sold in 7 ft 2 in, 8 ft 2 in, and 10 ft 2 in, so a building with standard 7 ft openings can run one part across every pair, in one finish. Mixed heights, which is common when a warehouse or loading area sits alongside office entries, mean two or three part numbers. Measure each frame before you consolidate the order rather than assuming the taller openings take the same post.
7) Can the Von Duprin 5654 mullion ship UPS or ground parcel?
No. At 7 ft 2 in on the shortest version and 10 ft 2 in on the longest, the 5654 exceeds parcel length limits and moves by freight truck, with freight charges on top. Worth knowing before you spec it for a single-door-count job, and worth batching with the rest of your hardware order if you can.
8) Is an aluminum mullion strong enough for a high-traffic commercial entrance?
The 5654 is an aluminum extrusion, which is the standard material for a removable mullion on aluminum and hollow metal openings: light enough that one person can lift a 10 ft 2 in post into place, stiff enough to carry the two 299 strikes and take device latching loads. If your opening is a fire rated pair, that is a separate question from material, since fire rated pairs require a mullion specifically listed for that use.
