ISC Alloy Swivel Snap Hook, Double Action and Three Way
ISC Alloy Swivel Snap Hook, Double Action and Three Way
A light alloy swivel snap hook from ISC Wales, built for rope access and fall arrest connections where line twist is a problem. The swivel body turns under load so rope and lanyard twist is not fed back into the attachment.
The three way version carries a 27 kN break strength and the double action version 25 kN, both with a 22 mm gate opening and an integrated fall indicator that shows when the hook has been shock loaded. The three way version weighs 200 g and the double action version 198 g, with overall dimensions of 195 x 70 mm. Choose the three way locking action where an accidental single movement must not be able to open the gate.
Browse the wider connector range in karabiners, maillons and hooks, or see the rope access collection for the descenders and ascenders these hooks are usually paired with.

What is the difference between double action and three way?
A double action hook needs two deliberate movements to open. The three way version adds a third, so the gate cannot be released by a single snag or accidental contact. Three way is the usual choice for rope access and rescue work.
What does the swivel do?
It lets the hook rotate under load, so twist in the rope or lanyard is not transmitted into the connection. That matters on suspended work where a worker turns repeatedly.
What is the fall indicator for?
It gives a visible sign that the hook has taken a fall load. A hook showing a triggered indicator must be removed from service.
