Von Duprin 050190-28 – Frequently Asked Questions

1) What does the Von Duprin 050190 bottom fitting do, and which mullion does it go on?
The 050190 is the floor-end fitting for a Von Duprin removable mullion, made for the 5654/5754 mullion. It's the base assembly the bottom of the mullion tube seats into and anchors down to, so the mullion has a fixed lower socket instead of just resting on the floor. It is a part, not a mullion, so you still need the 5654 or 5754 mullion tube itself.
2) What comes in the Von Duprin 050190 kit, or do I need to buy screws and anchors separately?
Everything for the bottom fitting is in the box: (1) bottom plate, (1) 5/16-18 x 1/2 inch socket head set screw, (2) 5/16-18 expansion anchors, and (2) 5/16-18 x 1-1/4 inch flat Phillips head machine screws. No separate fastener order. What is not included is the mullion itself or any top fitting hardware.
3) What drill size do I need in the floor to set the anchors for a Von Duprin mullion bottom fitting?
The anchors supplied with the 050190 are 5/16-18 expansion anchors, two of them, and they take the 5/16-18 x 1-1/4 inch flat Phillips head machine screws that ship in the same kit. Drill the floor to the anchor manufacturer's hole size for a 5/16-18 expansion anchor and set both. The 1/2 inch socket head set screw is the smaller one, it holds the mullion tube to the plate rather than the plate to the floor.
4) Can I use a removable mullion bottom fitting on a pair of doors instead of a mullion with no floor anchor?
That's what this part is for. A removable mullion on a pair of doors carries two rim exit devices, one per leaf, and the bottom fitting is the anchor point at the floor that keeps the lower end of the tube located and resisting push. On a 5654/5754 mullion the 050190 supplies that lower socket plus the expansion anchors to set it into the slab. If you cannot penetrate the floor, that is the constraint to solve before you pick the mullion, not something this fitting works around.
5) My mullion bottom plate is stripped and the mullion rocks at the floor, can I just replace the bottom fitting?
Yes, if the mullion is a 5654 or 5754. The 050190 is the genuine Von Duprin replacement for the bottom end, and because it ships with the bottom plate, the set screw, both anchors and both 1-1/4 inch machine screws, you can pull the old plate, re-anchor into fresh concrete, and reset the tube without sourcing anything else. The mullion tube and top fitting stay in place.
