Quality results require quality tools. wolfcraft uses the best materials and latest technologies to make its clamps: Steel parts are laser cut and induction heat-treated to reduce bending and flexing under extreme clamping pressure; Plastic parts are made from Nylon 6.6, which has 30% fiberglass content, giving it extra-long life and real durability. wolfcraft’s ratcheting band clamp is in a league of its own: While there are other band clamps out there, none have a ratcheting machanism or an automatic rewind mechanism. In addition, the strap is contained within a closed housing, ensuring the band never gets twisted. This is the best band clamp and the easiest one to use.
