Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N350-511 is a 1-inch zinc safety opening interlocking spring snap designed for quick, secure attachment in demanding field and marine environments. The interlocking safety mechanism prevents accidental disengagement under load, making it suitable for lifting, pulling, and mooring tasks where connection reliability matters. This snap is packaged loose and sold in a box of 5 units. Licensed tradespeople, farm operators, and marine service professionals routinely specify this type of hardware where a fast-connect solution is needed without sacrificing load retention.

This spring snap is rated for farm, marine, and recreational applications. Typical uses include securing lines and rigging during mooring operations, attaching tow or pull lines on agricultural equipment, and connecting recreational gear where repeated attachment and detachment are required.
