Product Description
Surface vertical rod devices secure at the head and threshold with rods visible on the door face. The standard configuration for double doors without a center mullion — each leaf latches independently into the header and floor.

This device is Right Hand Reverse. Exit devices are HANDED and cannot be reversed in the field. Stand outside the door facing it: hinges on the left = Left Hand, hinges on the right = Right Hand. If the door swings toward you, add "Reverse." Verify your handing before ordering.
Fire Rated (12- prefix) — This device is UL listed for fire-rated openings. Do NOT substitute a non-fire-rated device (8- prefix) on a fire-rated opening — your fire marshal will require removal and replacement.
Pro-Tip from Our Locksmiths: When specifying exit devices for double doors without a mullion, each leaf gets its own device. The active leaf (with the lock) gets the full device with trim. The inactive leaf gets a dummy push bar or flush bolt setup depending on the spec.
