Product Description
7827NL-313-4 Von Duprin 78 Series with 990NL Night Latch Surface Vertical Rod Exit Device in Duranodic Dark Bronze
The Von Duprin 7827NL-313-4 is a surface vertical rod exit device that latches at the header and threshold for pairs of storefront doors. Night Latch — outside lever locks and unlocks by key, inside always free for egress. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
The 7827 uses surface-mounted rods for top-and-bottom latching. Standard choice for pairs of doors where both leaves need to be active. Available in 4-foot width. Rods are visible on the door face. UL listed for panic exit hardware with hex key dogging standard. ANSI/BHMA A156.3 Grade 1 certified.
Pro-Tip from Our Locksmiths: Fire-rated 7827-F models lose mechanical dogging per UL code. If the customer needs doors to stay open during business hours on a fire-rated pair, you need magnetic hold-open devices tied to the fire alarm system. Budget that into the quote.
