Product Description
RX7847WDCNL-F-US15-4 Von Duprin Fire Rated 78 Series with 785NL Night Latch Wood Door Concealed Vertical Rod Exit Device in Satin Nickel
The Von Duprin RX7847WDCNL-F-US15-4 is a concealed vertical rod exit device that hides the rods inside the door stile for a clean, unobstructed look. 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 7847 provides top-and-bottom latching with nothing visible on the door face — the cleanest option for pairs of storefront glass doors. Available in 4-foot width. This is a handed device — verify LHR or RHR before ordering. 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: The 7847 concealed vertical rod is the cleanest look for pairs of wide stile storefront doors. The rods hide inside the door stile, so nothing shows on the face of the door. But concealed rods need precise alignment — if the door sags even 1/8 inch, the top rod won't engage the header strike.
