TETHRD VERSA LINKS 4 PK. VersaLinks have a 2.5? link spacing and are specifically designed for a larger button like the Lone Wolf stick button, Hawk Helium button, AlumiButtons, or other attachment buttons from 1.25? up to 2? at it’s widest point. They can be used anywhere an ultra strong daisy chain style strap would work. VersaLinks work very well with the Tethrd Predator Platform since the DynaLite™ fiber doesn’t stretch. VersaLinks are made of our DynaLite Ultra High Molecular Weight Polyethylene (UHMWPE) fibers. This is one of the strongest fibers on earth. Hunter’s get the benefit of incredible strength without sacrificing weight.
