Product Description
3548A-L-F-US4-4-RHR Von Duprin 3548A Series with 360L Lever Right Handed Fire-Rated Exit Device for Hollow Metal Doors in Satin Brass
The Von Duprin 3548A-L-F-US4-4-RHR is a fire-rated touch bar exit device for hollow metal doors 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 35A Series touch bar provides smooth, quiet operation with a clean look. The touch bar is non-handed and field-reversible — one SKU covers both LHR and RHR door swings. 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: Fire-rated hollow metal door installations have the tightest tolerances. The latch must engage the strike fully — no partial engagement. Test the latch throw before leaving the job site.
