How to install a non-adjustable zinc plated catch
Installing a non-adjustable over-centre latch is straightforward when the latch and catch plate are aligned correctly. Because this style has a fixed length, accurate positioning is important to ensure proper tension and secure closure.
01
Step 1 – Mark the latch position and mounting holes
Hold the centre latch in the closed position against the door, lid, or panel. Mark the screw or bolt holes, or weld points, ensuring the lever has room to operate, and the latch can move cleanly into the over-centre position.
02
Step 2 – Fit the catch plate to the opposing surface
Position the catch plate so the hook engages smoothly when the latch is closed. Fasten the plate securely to the frame or mounting surface using suitable hardware that matches the zinc plated steel finish.
03
Step 3 – Mount the latch and check hook alignment
Attach the over centre catch to the marked location. Because it is a non-adjustable latch, confirm the hook engages the catch plate correctly without excessive force or slack. Re-position if needed to achieve the right tension.
04
Step 4 – Test and refine the closure
Open and close the latch several times to ensure smooth lever action and a firm, repeatable hold. Adjust the mounting positions slightly if the closure feels too loose or too tight, ensuring long-term reliability under vibration or regular use.
