ISC Triple Action Swivel Snap Hook

The ISC triple action swivel snap hook combines a triple-action locking gate with a built-in swivel, so the rope can rotate without twisting the termination. Climbers use it on lanyards and climbing lines that spin as they move around the tree.

What the swivel buys you

Every time you move around the stem with a lanyard, the rope twists a little. Over a day those twists build up, the lanyard kinks, and the adjuster runs badly. A swivel at the snap lets the rope turn freely, so the line stays cleaner and the termination does not load awkwardly.

The triple-action gate keeps the same secure locking as the fixed ISC snap. If you want the plain version or other gate styles, compare our snap hooks.

Swivels are common on lanyard ends, positioning lines and lanyards used with mechanical adjusters that do not like twisted rope. Some climbers also use them on the end of a climbing line for the same reason. The trade-off is a little more weight and one more moving part to keep clean and check.

Setup and care

Have the snap terminated on your line by a qualified splicer or as ISC instructs. Use it within ANSI Z133 practice, and only after training with the system you are running.

Check the swivel turns smoothly with no grit or play, and the gate opens and locks on its own. Clean it with fresh water and let it dry. Retire it after a shock load, or if you find cracks, corrosion, bending or a sticky gate.
