Adjustable Over‑Centre Fastener — Zinc‑Plated Steel, Lockable with Catch

High‑holding, corrosion‑resistant over‑centre fastener with adjustable hook, pad‑lockable security and integrated safety catch — ideal for trailers, toolboxes, marine hatches, and industrial enclosures.

Product overview

This adjustable over‑centre fastener is made from zinc‑plated steel for reliable corrosion protection and long service life. The over‑centre toggle delivers strong clamping force with minimal handle travel, while the threaded, adjustable hook lets you fine‑tune tension. A pad‑lockable hole and positive safety catch prevent accidental opening under vibration or load.

Key features

• Adjustable tension: Threaded hook and lock nut for precise clamping.
• Lockable security: Pad‑lockable hole secures lid or door against tampering.
• Safety catch: Positive catch prevents accidental release during transport.
• Compact action: Over‑centre geometry gives high clamp force in a short stroke.

Technical specifications

Note: Confirm hole pattern and panel thickness before installation to ensure correct fit.

Installation and maintenance

• Mounting: Use appropriate countersunk or through bolts sized for 4.2 mm holes; tighten securely.
• Adjustment: Set clamp tension by turning the threaded hook and locking with a nut or nyloc to prevent loosening.
• Locking: Insert a standard padlock through the lock hole to immobilise the latch.
• Care: Clean and lightly lubricate pivot points periodically; inspect zinc plating for wear in harsh environments.

Applications

Perfect for trailers, ute trays, toolboxes, camper canopies, marine hatches, truck bodies, and industrial access panels where a compact, secure, adjustable clamp is required.
