Product Description
5547WDC-TL-F-US10B Von Duprin 5547 Series with 550DT/376WDC-T/10WDA Turn Lever Fire Rated Wood Door Concealed Vertical Rod Device in Oil Rubbed
The Von Duprin 5547WDC-TL-F-US10B is a narrow stile concealed vertical rod exit device that hides the rods inside the door stile for a clean, unobstructed look on glass and aluminum doors. Turn Lever — outside lever turns to retract latch. Thumbturn operation provides passage without a key. No cylinder required for this function.
The 5547 is the top-and-bottom latching version of the 55 Series — it secures at the header and threshold instead of the strike jamb, making it the standard choice for pairs of narrow stile doors. Concealed rods mean nothing shows on the door face. 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 5547 concealed vertical rod is the cleanest look you can get on a pair of narrow stile glass doors. The rods hide inside the stile, so there's nothing visible on the door face. But concealed rods need precise alignment — if the door sags even 1/8", the top rod won't engage the strike.
