Determines strength retention in the MightyLock line-locker ring.

We have a Mightylock installation at both ends of the webbing. The webbing is wrapped around the MightyLock in the Right-Side-Up configuration and anchored to either a 5/8" Van Beast Shackle (if it's a 25mm/1-inch webbing) or a 1/2" Van Beast Shackle (if it's a 19-20mm webbing). The tails are kept to a minimum on both ends (75 - 150mm (3 - 6 inches)).

  • Sample Length - 1.5 m (5 ft)

  • Pull Rate - ~350 mm per minute
