We ran a very limited number of GRIP6 Uli belts to support Paul on the road this year. These belts were exclusively stamped with the Uli shield logo. GRIP6 belts are designed to take full advantage of the material properties used in the construction of the belt. The belts hold incredibly well and that's why they have been given the "badgerbite" name. Once a GRIP6 belt is locked in place, it will hold over 250 lbs of outward pressure with its proprietary Fuselock Technology. These belts are manufactured with certified 6061 T6 aluminum. As for the belt's construction, most nylon belts are made from Nylon 6. Companies tend to choose this material because it is less expensive than GRIP6 straps which are made from Nylon 6,6. This material is more rigid, has higher tensile strength, superior abrasion resistance and can withstand higher temperatures before melting. This is an adjustable belt so its one size fits all.
