When a standard 63mm backset isn't enough, the Eclipse Bolt-Through Tubular Mortice Latch in Matt Black — 76mm delivers the extra clearance needed for doors with wider stiles, offset handle positions, or specific architectural door preparations. The 76mm backset — measured from the door edge to the centre of the spindle hole — is the specification to reach for when lever handles need to sit further from the door edge, ensuring comfortable operation and a balanced visual appearance on wider-stile doors.

Like all Eclipse bolt-through tubular latches, this latch installs into a drilled hole in the door edge for a completely concealed fit, leaving the door face clean and uninterrupted. The sprung latch bolt retracts when the lever handle is operated and springs back to engage the keep on closing, providing smooth, reliable passage door operation. The Matt Black (MBK) forend and face plate pair naturally with black, black antique, and gunmetal door furniture, maintaining a consistent finish at the door edge.

A practical choice for interior doors in period properties with thicker door frames, bespoke joinery, or any installation where the 63mm backset falls short. Part of the Eclipse tubular latch range, available in multiple backset sizes and finishes.
