Auto glass shops have used wire to remove bonded glass ever since manufacturers started “gluing” them in years ago. For years window technicians used anything that would work; guitar strings, piano wire, etc. TightWire (TW72) is designed to cut urethane with ease. Our customers are happy with the power and durability of this tool from Equalizer. The wire on this tool is composed of three super-strong stainless steel wires braided to form a powerful and durable cutting tool. It is anodized to a smooth finish and has a distinctive gold color. The diameter of the wire is .022 inches. It is made in USA.
