ISC HMS Quadlock Karabiner

ISC HMS karabiners are gorged for best build quality and feature a unique "blind" nose, which improves performance by reducing snagging. The barrels have been designed with a square cut notch to limit debris build up. This is 7075 Aluminium HMS rated to 27kN.

The QUADLOCK system is also extremely secure, and involves a 4 step process to open the gate: Turn - Lift - Turn - Push - Open.
