AMS DLLH-54 Operates Dual Locks From Single Lever On Narrow Door Jambs.
AMS DLLH-54 Operates Dual Locks – AMS Australia’s DLLH-54 Series dual lock lever handle is a narrow-style door hardware solution designed to operate 2 locks from a single lever action.
Developed in Australia, the DLLH-54 combines a latch and swing bolt arrangement and according to AMS, it’s the first lever lock and swing bolt combination designed to provide this functionality on narrow-style frames.
The system addresses an operational issue with dual-lock doors, which can otherwise require a 2-handed action to release both locks. With the DLLH-54, a single downward movement of the lever releases both locks simultaneously.
The DLLH-54 is designed for use with Lockwood locks and incorporates a heavy-duty lever return spring, adjustable external escutcheon and concealed external fixings. The internal and external handles are supplied as a pair.
AMS has also developed the DLLH-54 T version, which incorporates an internal turn snib. This allows the upper deadbolt to be activated from inside the door using the snib without affecting normal operation of the lever. A single downward movement of the handle continues to release both locks simultaneously.
