The ISC SH905 triple-action swiveling snap is a 'world first'. The ISC SH905 Snap requires three separate actions to open so now meets the needs of tree climbers - easily opened with one hand, great for fliplines and lanyards. The swivel works particularly well with wirecore fliplines, allowing you to rotate the snap into position without torquing the wirecore. Fall indicator fitted as standard - in the event of a fall, the red ring is exposed, alerting the user that a fall has taken place.
