Spring Loaded Stainless Over Centre Fastener

Large Spring-Loaded Over Centre Latch – 304 Stainless Steel with Fail-Safe Security

The Dunn & Watson large spring-loaded over centre fastener takes the reliability of a traditional toggle latch and enhances it with two key upgrades: built-in safety and secure stowage. Featuring a dual spring mechanism, this latch not only prevents accidental decoupling under load with its Fail-Safe feature but also snaps flat when disengaged to prevent damage or injury with its Snap-Flat action.

Made from corrosion-resistant 304 stainless steel and offering an adjustable range of 36.5mm to 61.5mm, this heavy-duty latch is ideal for trailers, utes, campers, and industrial applications where strength and safety are paramount.

The spring loaded over centre fastener is a secure way to fasten doors and lids. The tension on the spring keeps the arm and handle flat and prevents rattling, greatly reducing the chance that the latch opens in transit. This fastener is made from 304 stainless steel and has an adjustable arm.
