Zinc plated over centre hardware for reliable tensioning
These adaptable over centre latches are made from mild steel with a durable zinc plated finish, providing strong corrosion resistance and dependable performance in trailer, gate, and industrial applications. The lever-and-hook action creates firm tension, drawing the catch plate tight to secure panels, lids, or doors in place.
With multiple sizes available, this centre fastener range suits medium-duty fastening where a consistent, repeatable closure is essential. The adjustable design allows precise tuning of latch tension, offering a practical, long-lasting fastener for workshops, vehicles, and general hardware use across Australia.

These adjustable over-centre latches are commonly used on tray backs, trailers, trucks, gates, toolboxes, and equipment panels where a firm, repeatable closure is essential. Their zinc plated steel construction provides dependable performance in both transport and workshop environments.

Install with confidence
How to install an adjustable zinc plated catch
Installing an adjustable over centre latch is straightforward when the latch and hook are aligned correctly. Always check the latch dimensions, mounting length, and required tension before fitting it.
01
Step 1 – Position the catch and mark the fixings
Hold the overcentre catch against the door, lid, or panel in the closed position. Mark the screw or bolt holes and ensure the lever has enough clearance to operate smoothly when locked and unlocked.
02
Step 2 – Fit the catch plate to the opposing surface
Align the catch plate so the hook engages cleanly when the latch is closed. Fasten the plate securely to the frame or mounting surface using suitable screws or bolts to match the zinc-plated steel hardware.
03
Step 3 – Attach the latch and adjust the tension
Fix the adjustable latch to the marked position, ensuring the hook reaches the catch plate without excess force. Use the adjusting screw or threaded section to fine-tune the tension until the latch pulls the two surfaces together firmly.
04
Step 4 – Test the closure and re-adjust if required
Open and close the latch several times to confirm smooth operation and consistent locking pressure. Adjust the hook length or tension if the closure feels too loose or too tight, ensuring a reliable medium-duty hold.

FAQs about adjustable over centre catches
How do I select the right latch for me?
Start by considering the duty rating, size, and the amount of tension you need. For trucks, motor homes, utes, tray backs and camper trailers, choose a latch that matches the required closure strength and mounting length. Adjustable over centre latches are ideal when you need fine control over tension, while fixed models suit simpler applications.
