Installing over centre catches is straightforward, the process ensures consistent tension, correct alignment and long-term performance across any door, panel or hatch.
02
Step 1: Position the centre fastener correctly
Begin by aligning the latch body with the panel or door edge. Check that the centre hooks line up with the catch plate position to ensure smooth lifting and locking during operation.

Step 2: Mark and drill mounting points
Use the correct size drill bit to prepare the mounting holes for the latch and catch. Ensure all points are marked accurately so the fastener operates with the correct centre tension once installed.

Step 3: Install latch and catch components
Fix the latch and catch plate using appropriate hardware for your material type. Tighten each fastener evenly so the centre latch engages cleanly without excessive resistance or looseness.
05
Step 4: Test tension and secure operation
Lift and lock the latch several times to confirm smooth overcentre movement. Adjust the catch plate position if needed to achieve firm tension and secure doors without over-compressing the seal.
