Product Overview

WEST MARINE ISAF/ISO Specification 12401 Double Safety Tether

Elastic double tether has a 3' leg that extends from 18" to 36", plus a 6' leg that extends from 41" to 72". Incorporates lightweight aluminum double-action safety hooks, built-in stress indicator. With a 3' leg and a 6' leg, you have two options for safely tethering yourself. Short leg provides the highest security, and 6' leg allows you to stand or move around while safely clipped on.


  • Includes a bright overload indicator flag embedded in the stitching that is exposed when the tether is stressed to the point of needing replacement (about 900lb. of force triggers the flag)
  • The boat-end aluminum safety hook has an easy-to-use double-action gate that automatically locks closed, so it won’t accidentally release from attachment points
  • Double-action gate is extremely easy to open in one ergonomic movement without pinching your hands
  • Internal elastic located inside the webbing cover retracts when not under load, staying out of the way
  • Non-magnetic, stainless steel auto-locking carabiner at chest end connects securely to the harness
