What is the difference between the 98 and 99 series parts?

The 98 and 99 series use identical internal replacement parts. The only physical difference is the exterior mechanism case: the 98 series has a smooth case and the 99 series has a grooved case. Any dogging component, center case, latch assembly, or electrified kit ordered for the 98 fits the 99 of the same configuration and manufacture date.

How do I find the correct center case part number for my 98/99 device?

Confirm your device configuration first. Rim configurations (98, 99, F-98, F-99) use center case 109012 for the standard assembly. SVR configurations (9827, 9927) use 109358. These two part numbers are not interchangeable. The center case cover kit for rim devices is part 050071. Always confirm configuration before ordering any center case component.

What dogging parts do I need for a post-1998 Von Duprin 98/99 device?

For devices manufactured after 1998, the current-spec dogging components are: 090040 (hex dogging shaft), 090042 (dogging adapter spring), and 090043 (dogging adapter). Devices manufactured before 1998 use a different shaft profile and require the old-style replacement kit (part 050709) instead.

Which Chexit PCB kit do I need for a 98/99 Chexit device?

The PCB kit depends on the device manufacture date. Devices manufactured after August 24, 2015 use the current-generation modules: 040086 for 15-second release, 040088 for 30-second, or 040089 for 0-second delay. Devices manufactured before August 24, 2015 use the discontinued 050228-series PCB kits. Check the manufacture date stamped on the device body before ordering.

What is the QEL conversion kit for the Von Duprin 98/99 rim device?

The 114317 QEL Modular Conversion Kit adds quiet electric latch retraction to a mechanical 98/99 rim device without replacing the device body. For Allegion Connect integration, use 040061 instead. For SVR devices, the QM retrofit kit is 47263418.
