Description
The Von Duprin 889-R US10B is a replacement exit device trim required when 373L electronic controls are paired with sex bolts on wood or composite fire doors. The four studs on the cover plate enable secure through-bolting to the device center case, ensuring reliable operation on fire-rated applications where standard fastening methods are not permitted.
This trim is engineered for compatibility with Von Duprin 373L control systems and sex bolt assemblies. Installation requires proper alignment with your exit device center case and fire door construction. As an authorized Von Duprin dealer, E.D. Locks offers expert guidance on fire door hardware compatibility and installation best practices.
