The Equalizer® Urethane Cutting Knife (TLS1214) is 24" long and 1/4" wide. It was designed to help the window technician with the extra-long dashboards in vehicles today. Measuring a full 24" long, the TLS1214 can reach the farthest corners of the windshield with ease. These heavy-duty knives from Equalizer® have replaceable parts and blade tightening capabilities. Both knives come with the unique “hide-a-blade” design that allows you to store an extra blade in the handle for quick replacement. Made of high quality, lightweight aluminum with a steel retaining block for the blade, this comes with one standard utility knife blade. Replacement retaining blocks and screws are available through Equalizer®. It uses all standard utility knife blades. Made in USA.
