Description
The Von Duprin 889-M US4 is a exit device trim required when 373L 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 fastening on fire-rated door assemblies where standard bolting methods are not suitable.
This trim is designed for professional installation on Von Duprin exit devices and fire door applications. For compatibility verification, keying options, and installation guidance specific to your door type, contact our authorized dealer specialists at sales@edlocks.com or 1-877-207-6067.
