Protex Fasteners’ 43 and 44 series latch products are suitable for agricultural, industrial, earthmoving and process equipment sector applications.

The company has extended its range of heavy-duty over-centre latches with the introduction of three new products for high-strength, re-sealable fastening applications.

Protex 43-3292, 43-4292 and 44-4292 feature all-riveted mounting baseplates that enable assembly loads to be distributed over a large bearing area, The fasteners are fully compatible with Protex 40 and 41 series latches and are offered in stainless or zinc-plated mild steel – achieving ultimate tensile strengths of 2,000 and 2,500kgf respectively, with type 04-4292 catchplates.

All models provide up to 20mm of grip range adjustment as standard and can be sealed using lock wire or self-retaining pins.

Both 43 series products can be padlocked for added security, while the 44-4292 is fitted with a patented, side-action catch that locks automatically when the latch is closed.

Application versatility is further increased on 43-4292 and 44-4292 models through an optional 150mm-long eyebolt, which increases the grip range adjustment of each product to 60mm.
