Von Duprin 50275 – Frequently Asked Questions

1) Is the Von Duprin 50275 auxiliary bolt handed, and does right-hand mean the hinges are on the right?
Handing matters on this part. The 50275 is the right-hand (RH) auxiliary bolt only, and it will not orient correctly on a left-hand device. Door handing is determined from the outside of the door: standing outside, an RH door has hinges on the right and swings away from you. If your 88 Series device is left-hand, you need the LH version of the bolt instead, not this one.
2) I need a top latch or rod for a non-Von Duprin exit device. Can I use this bolt?
No. The 50275 is an 88-F Series auxiliary bolt and is brand and series specific. For other makes, match the part to the device: Accentra 7110/7120 and 7110F devices have their own top latch replacement components, Falcon T Series uses a 2-3/8 inch square corner deadlatch part, and Falcon 24 Series Monarch F-25-C and F-25-CWDC devices take the 610061 concealed vertical top rod. Exit device internals are not interchangeable across brands.
3) Can an Accentra 7110F top latch be used in place of the Von Duprin 50275 auxiliary bolt?
No. The Von Duprin 50275 is an auxiliary bolt for 88F Series exit devices, set up for right-hand doors. The Accentra 60-7010-0050-999 is a top latch replacement component for the Accentra 7110F exit device, a different brand's device and a different part within the device. Each is built to its own manufacturer's exit device chassis, so they do not interchange.
4) What does the auxiliary bolt on an 88 Series exit device actually do?
It provides an auxiliary deadlocking function. When the door closes, the bolt engages against the frame and deadlocks the latch so it cannot be shimmed or forced back, and it also keeps the latch aligned for consistent operation. If yours is worn or broken, the device may still push open but the latch loses its anti-shim protection and can rattle or mis-align.
5) Is the 50275 just the bolt, or a whole latch assembly for the exit device?
It is the auxiliary bolt component only, not a complete latch or a full device. Order it when you are rebuilding an existing 88-F device and the auxiliary bolt itself is worn, bent, or missing. If the whole latch head is damaged, the bolt alone will not fix the opening.
6) Does using an OEM Von Duprin bolt matter on a fire exit device?
Yes, and it is the main reason to buy this part rather than a generic one. The 50275 is a genuine Von Duprin OEM component for the 88-F fire exit device, so the device is rebuilt with the part it was built around. Substituting non-OEM internals in a fire exit device is what gets a repair flagged on inspection in healthcare, education, and government facilities.
7) If the Von Duprin 50275 auxiliary bolt is not the fix for a pair of doors that will not secure, what else should be checked?
The 50275 addresses the auxiliary deadlocking bolt inside an 88F Series device on a right-hand door. On a double-door opening the problem is often the mullion rather than the device: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers support exit device mullions. Those are opening-level components, not parts of the 88 Series device.
8) Is the Arrow 16RCR-27 rim housing an alternative to the Von Duprin 50275?
No. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing for the Arrow 24/25 Series, a cylinder component that carries the key core. The Von Duprin 50275 is the mechanical auxiliary bolt inside an 88F Series device. A locksmith rekeying a device needs the cylinder housing; one restoring deadlocking action on an 88F needs the auxiliary bolt.
9) Will a steel auxiliary bolt hold up on a high-traffic exterior door?
The 50275 is steel with a corrosion-resistant zinc/metallic finish, which is why it is specified for high-traffic commercial openings such as schools, hospitals, retail, warehouses, and municipal buildings. It is a concealed internal component, so the finish is about corrosion resistance rather than matching the visible trim on your door.
