Von Duprin 963579 – Frequently Asked Questions

1) What exactly is the Von Duprin 963579 part?
It's a fastener, not an assembly. The 963579 is a 12-24 x 3/8 inch UFPHMS (under flat pan head machine screw) sold as a genuine Von Duprin replacement part for 880NL/DT Series exit device hardware. If you're looking for a latch, trim, or chassis, this is not it.
2) Will the Von Duprin 963579 screw fit exit devices other than the 880 series?
It is specified for the Von Duprin 880NL/DT Series and that is the fit Von Duprin states. For a 98/99, 33A/35A, or other Von Duprin series, order the screw called out in that device's own parts breakdown rather than assuming the 12-24 x 3/8 will thread the same.
3) Can I just use a hardware store 12-24 screw instead of the Von Duprin 963579?
The thread size is common, but the head is the part that matters. A UFPHMS has a low, flat pan head that sits where the 880NL/DT trim and device components need clearance. A standard pan or truss head of the same 12-24 x 3/8 thread can stand proud and interfere. That's why Von Duprin calls this part out specifically as OEM.
4) I'm restocking service truck parts for Von Duprin 880 night latch and dummy trim - what is the 963579 used for?
It's the 12-24 x 3/8 UFPHMS mounting screw in the 880NL/DT parts breakdown, the kind of fastener that gets stripped or lost during a trim swap or a lock service call. Stocking a few means a trim reinstall doesn't stop because a screw walked off. Model number to order by is 963579.
5) Does ordering the 963579 include any other 880 series parts?
No. The 963579 is a single fastener component, not a kit. Any trim, latch, or device body you need for the 880NL/DT has to be ordered separately under its own Von Duprin part number.
6) Is the 963579 suitable for high-traffic commercial openings like schools and hospitals?
Yes. It carries a Heavy Duty rating and is classified for commercial use, which is the service level exit devices in schools, healthcare, government buildings, and multi-tenant residential are maintained to.
