Product Description
3550A-WDC-L-F-US26D-4-LHR Von Duprin 3550A-WDC Series with 360L Lever Left Handed Fire Rated Wood Door Concealed Cable Device in Satin Chrome
The Von Duprin 3550A-WDC-L-F-US26D-4-LHR is a touch bar wood door concealed vertical cable exit device from the 35A Series family. Lever Trim — outside lever retracts the latch for entry. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
The 3550A-WDC uses a steel cable instead of rigid rods for top-and-bottom latching. The cable system is more forgiving of slight door misalignment, making it a practical choice when perfect door alignment can't be guaranteed. Available in 4-foot width. UL listed for fire exit hardware — no mechanical dogging on fire-rated models. ANSI/BHMA A156.3 Grade 1 certified.
Pro-Tip from Our Locksmiths: Wood door concealed cable (WDC) models are specifically designed for wood doors — the cable routing and mounting are optimized for wood door construction. Don't install a standard cable device on a wood door or vice versa.
