The Eurospec Bolt-Through Tubular Latch is an essential hardware component designed for professional installers and homeowners who need a reliable, smooth-operating latch for lever-on-rose door handles. It offers the distinct advantage of bolt-through mounting, which ensures handles are securely fastened to the door, though it is specifically engineered for doors requiring a 64mm backset.

The dust box provides a clean, professional finish for the strike plate cutout and prevents debris from falling into the frame.
Check if the strike plate is misaligned with the latch bolt, causing friction.
Adjust the strike plate tab slightly to tighten the latch fitment or ensure the dust box is seated correctly.
Verify that the bolt-through screws are properly tightened through the latch body and into the rose fixing holes.
Installation requires a standard mortise chisel set to create the 64mm backset pocket. Ensure the door edge is pre-drilled to the correct diameter before inserting the latch. When installing the strike plate, ensure the plastic dust box is inserted into the door frame cavity first to ensure a rattle-free closure. To maintain the mechanism, it is recommended to apply a light silicone-based lubricant to the latch bolt once a year, avoiding any harsh chemical cleaners that may damage the black finish.
