National Mfg N830-309 3/4 Inch Zinc Safety Spring Snap

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-309 is a 3/4 inch zinc safety opening interlocking spring snap built for demanding quick-attachment applications. The interlocking safety mechanism prevents accidental release under load, making this snap appropriate for lifting, pulling, and mooring tasks where a standard spring snap would not provide adequate retention. Zinc construction offers corrosion resistance suitable for outdoor and marine environments. This hardware is sold as a package of 5 units and is boxed loose for easy distribution across job sites or service vehicles.

This spring snap is designed for use across a range of farm, marine, and recreational applications where fast, secure connections are required. Typical use cases include mooring lines, rigging attachment points, tow lines, gate latches, and equipment tie-downs. The safety opening interlocking design adds a secondary retention step beyond a standard gate, reducing the risk of unintended disconnection during dynamic or sustained loading. Suitable for light-duty lifting and pulling tasks in agricultural and marine settings.

Installation Notes

Installation and attachment should be performed by a qualified person familiar with rigging and load-bearing hardware. Always verify that the snap gate is fully engaged and locked before applying any load. Inspect the snap body and gate for wear, cracking, or corrosion before each use, and replace immediately if damage is found. Never exceed the rated load capacity of the snap or the weakest component in the connected assembly.
