Von Duprin 900597 26D – Frequently Asked Questions

1) Will the 900597 end cap screws fit a Von Duprin 88 or 98/99 Series exit device?
No. The 900597 screw package is built for the 33A and 35A Series end cap assemblies and nothing else in the Von Duprin line. Von Duprin part numbers for end cap hardware are series specific, so a 98/99 or 88 device needs the part called out for that series. Check the device number stamped on the touchpad rail before ordering.
2) Can I use the 900597 screws on a fire rated exit device opening?
The 900597 screw package is not carried as a fire rated component. On a fire rated opening the whole assembly, device and all listed parts, has to stay within the door's listing, so a labeled door needs the fire rated part number called out for that assembly. On a non-rated opening in a school, office, or warehouse, the 900597 is the correct end cap fastener for a 33A or 35A device.
3) What is the Falcon equivalent of a Von Duprin 900597 end cap screw package?
There is no direct Falcon screw package that swaps into a Von Duprin 33 or 35 Series end cap. The 900597 is a genuine Von Duprin replacement fastener set made for the impact resistant end caps on 33A and 35A devices, and the fastener pattern is specific to that end cap casting. The Falcon exit device service parts that cover a different part of the device are things like the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, and the Falcon 23981160 T Series 2-3/8 inch square corner deadlatch replacement part. Those replace rods and latches, not end cap hardware, so for an end cap repair on a 33 or 35 device the Von Duprin package is what matches the device.
4) My exit device latch is worn, not the end cap. What part do I order instead of the 900597?
The 900597 only restores the fastening of the end cap assembly on Von Duprin 33A and 35A devices; it does nothing for a worn latch. For latch work, the part depends on the device brand. Accentra publishes top latch replacement components for its exit devices: the 60-7010-0049-999 top latch replacement component for 7110/7120 devices, and the 60-7010-0050-999 top latch replacement component for the 7110F. Falcon's 23981160 is a T Series 2-3/8 inch square corner deadlatch replacement part. Match the replacement latch to the device family already hung on the door rather than to the end cap fastener package.
5) Is the Von Duprin 900597 Grade 1 hardware suitable for a high traffic commercial door?
Grade 1 and commercial rated, which is the level a facility manager wants on a high traffic exit. The impact resistant end cap on a 33A/35A device is the part that takes the hit from carts, gurneys, and door stops, and these are the fasteners that hold it. That is why it turns up on hospital, school, and warehouse service calls more than anywhere else.
6) Do I need the full end cap or just the screws for a loose Von Duprin 33A end cap?
If the cap itself is intact and only the fasteners are stripped, missing, or backed out, the 900597 screw package alone puts it right. If the cap is cracked or deformed from impact, screws will not hold it and the end cap assembly has to be replaced. Pull the cap and look at the screw bosses before you order, because a stripped boss in the rail is a different repair again.
7) Can I substitute generic machine screws for the Von Duprin 900597 end cap package?
Not advisable on a 33A or 35A. The end cap fasteners are sized to the rail bosses and to the impact resistant cap design, and a hardware store screw of the wrong length or head profile either bottoms out or sits proud where the pushpad travels. The 900597 is the genuine Von Duprin package for that assembly, which is the point of specifying it on a Grade 1 commercial device.
8) Does the Von Duprin 900597 carry a fire rating like other exit device service parts?
The Von Duprin 900597 is a Grade 1 commercial part and is not fire rated. Several comparable exit device service parts are in the same position: the Accentra 60-7010-0049-999 top latch replacement component for 7110/7120 devices is not fire rated, and neither is the 60-7010-0050-999 for the 7110F. If the opening is a fire door, the rating is carried by the labeled device and door assembly, so confirm the device itself is the fire rated model before specifying service parts for it.
9) I need to secure a pair of doors, not repair an end cap. What should I be looking at?
A screw package like the Von Duprin 900597 is an end cap service part for 33A and 35A devices and has no role in a double door opening beyond the device it is fastened to. For a pair of doors with exit devices, the part that carries the second leaf is a mullion: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 is a set of aluminum mullion stabilizers for exit devices. Order the mullion by the opening width and the device it is paired with, and keep the 900597 on the list only if the end cap hardware on the 33 or 35 device also needs restoring.
10) Is a rim cylinder housing an alternative to the 900597 when servicing an exit device?
They solve different problems. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing in the 24/25 Series, and it is what you order when the keyed rim cylinder side of a rim exit device needs to be replaced or rekeyed to a small format interchangeable core system. The Von Duprin 900597 is a fastener package for the impact resistant end caps on 33A and 35A devices and has nothing to do with the cylinder. A device that is both loose at the end cap and needs a new core takes both parts, each matched to its own device series.
11) What other Von Duprin or exit device replacement parts might I need alongside the 900597 screws?
Depends on what failed. The 900597 covers only the end cap fasteners. For latch problems on other brands of device, ZenSupply stocks parts like the Accentra 7110/7120 top latch replacement component and the Falcon T Series 2-3/8 inch square corner deadlatch. For a pair of doors with rim devices, the Falcon 4023 steel mullion and Falcon 525 aluminum mullion stabilizers cover the mullion side. None of those interchange with a Von Duprin 33A or 35A, but they are the equivalent repair on those lines.
12) For a concealed vertical rod exit device, is the 900597 the right service part?
Only for the end cap. The Von Duprin 900597 is the impact resistant end cap screw package for 33A and 35A Series devices, so it addresses the end cap assembly regardless of the latching arrangement. The rod itself is a separate part number by brand and device: Falcon publishes the 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices for that role. Diagnose whether the fault is the top rod adjustment or a loose end cap before ordering, since the two parts are not interchangeable.
13) How do I match the finish of a replacement screw package to the exit devices already in my building?
The Von Duprin 900597 end cap screw package comes in 626 satin chrome, 625 bright chrome, 612 satin bronze, 605 bright brass, and 710 dark bronze, so it can be brought in line with the finish of the 33 or 35 Series devices already hung. Comparable service parts from other brands are published by device family rather than by a matching finish range, for example the Falcon 4023 steel mullion and the Falcon 525 aluminum mullion stabilizers, which are ordered to the opening. Where an end cap is visible at eye level in a lobby or corridor, order the screw package in the finish already standard across the facility.
