Von Duprin VON-050459 – Frequently Asked Questions

1) My 55 Series push bar feels loose and rattles. Do I need a whole new exit device?
Often not. Where the looseness is in the crossbar itself, the 050459 reinforcement kit is the repair Von Duprin sells for exactly that condition on 55/88 Series devices with a 37 inch crossbar. It lets a maintenance crew bring the device back to proper operation in place. If the latch mechanism or end case is the problem, the crossbar kit will not fix it.
2) Can a Falcon exit device replacement part be used in place of the Von Duprin 050459 crossbar reinforcement kit?
No. The Von Duprin 050459 is a 37 inch crossbar reinforcement kit built for the Von Duprin 55/88 Series, so it is matched to that series' crossbar geometry. Falcon's exit device replacement components cover different devices entirely: the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series, and the Falcon 610061 is a concealed vertical top rod for the 24 Series Monarch F-25-C and F-25-CWDC devices. Neither touches a crossbar, and neither is dimensioned for a 55/88 Series device. If the crossbar on a 55/88 Series unit is the part that has failed, the 050459 is the component to order.
3) My crossbar exit device is failing on a pair of doors. Do I need the 050459 or a mullion?
They solve different problems. The Von Duprin 050459 is a 37 inch crossbar reinforcement kit that restores the structural integrity of the crossbar on an existing 55/88 Series exit device, so it is the answer when the bar itself is flexing or worn. A mullion is a separate vertical member installed between a pair of doors to give rim devices a strike surface: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 is a set of aluminum mullion stabilizers. If the doors are sagging apart at the meeting stile, the mullion hardware is the fix; if the bar on the device is the weak point, the 050459 is.
4) What does a crossbar reinforcement kit actually do on a 55/88 Series exit device?
It stiffens the crossbar, the horizontal push bar a person hits to exit. On high traffic openings the crossbar takes abuse and can flex or rack over time, which makes the device feel sloppy and eventually keeps the latch from retracting cleanly. The 050459 is a replacement part that restores the crossbar's rigidity so the device operates the way it did new, without swapping out the entire exit device.
5) Is this part heavy duty enough for a school or hospital main entrance?
Yes. The 050459 is a Grade 1, commercial rated component, which is the heaviest duty classification for door hardware and the level specified for high traffic institutional openings such as schools, hospitals, government buildings and retail entrances. Grade 1 is the same level the 55/88 Series devices themselves are built to.
6) I need parts for a non Von Duprin exit device. Does the 050459 cross over?
It does not. The 050459 is a Von Duprin specific crossbar component and will not fit another manufacturer's device. For other brands ZenSupply carries their own replacement components, for example the Accentra 7110/7120 top latch replacement, the Falcon T Series 2-3/8 inch square corner deadlatch, and the Falcon 610061 concealed vertical top rod for F-25-C and F-25-CWDC devices. Match the part to the brand and series on your door.
7) Is the Von Duprin 050459 an option for a fire rated opening?
The 050459 crossbar reinforcement kit carries a fire rating of No, and it is a Grade 1 commercial replacement part for the 55/88 Series. Several comparable exit device replacement components are in the same position: the Accentra 60-7010-0049-999 top latch component for 7110/7120 devices and the Accentra 60-7010-0050-999 top latch component for the 7110F both carry a fire rating of No. On a labeled opening, the device and every component in it have to be listed together, so that is a question for the device's own label rather than a part selected on its own.
8) What is the difference between the Von Duprin 050459 and the Accentra 7110/7120 top latch replacement component?
They repair different parts of an exit device and belong to different device families. The Von Duprin 050459 is a 37 inch crossbar reinforcement kit for Von Duprin 55/88 Series devices, addressing the push bar itself. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110/7120 exit devices, and the Accentra 60-7010-0050-999 is the equivalent top latch component for the 7110F. A top latch is the latching point at the head of the frame on a vertical rod device, not part of the crossbar assembly, and the Accentra components are dimensioned for Accentra hardware.
9) Do I need the 050459 crossbar kit if the problem is that the key cylinder will not turn on my rim device?
No, that is a cylinder housing issue rather than a crossbar issue. The Von Duprin 050459 reinforces the 37 inch crossbar on a 55/88 Series exit device and has no role in the keyed side of the hardware. For small format interchangeable core rim cylinder work, the Arrow 16RCR-27 is a 6/7-pin SFIC rim housing in the 24/25 Series. Order the 050459 when the push bar needs reinforcement and the cylinder housing when the keyed access is the failure.
10) I am standardizing exit hardware across a property. Is a crossbar kit the right stock item to keep on the shelf?
It is a sensible MRO stock line if your buildings run Von Duprin 55 or 88 Series crossbar devices at a common door width. Keeping the 050459 on hand means a flexing push bar gets repaired on the spot rather than waiting on a full device replacement. Stock it by crossbar length, since a single length only covers the openings that match it.
