Description
The Von Duprin 889-V US4 is an exit device trim required when 373L controls are used with sex bolts on wood or composite fire doors. Four studs on the cover plate enable through-bolting directly to the device center case, ensuring secure and compliant installation on fire-rated door assemblies.
Verify compatibility with your specific 373L control and door construction before ordering. For detailed installation guidance, keying assistance, or to confirm fit with your existing hardware, contact our expert team at sales@edlocks.com or call 1-877-207-6067. As an authorized Von Duprin dealer, we ensure you receive genuine parts and professional support.
