Locking ties are perfect for securing wrap to pipes with its self-locking design. Locking ties offer many other uses including bundling wires, hoses and other forms of insulation products. Just slide end into locking mechanism and pull tight. Tightening locking ties just got easier with DEI's easy to use locking tool. Both lightweight and strong locking ties can take a lot of abuse but are sometimes hard to work with. This is why DEI developed their locking tie tool. Simply slide the tool on the end of any 1/4" nut driver, engage the tie, and twist. This gets the tie nice and secure without any hassle.
