This KESON long tape measure features a blade with 2 coats of PVC—one coat to bind the fiberglass strands, the second coat to help protect the lettering from wear away. The lightweight blade is rust-resistant and will not conduct electricity, making it an excellent choice for use in corrosive environments and in areas with electrical hazards. The open reel design can be easily cleaned of dirt and debris, so it’s ideal for use in dirty, dusty, or outdoor environments. The double-throat rollers guide the blade return and prevent the tape from twisting. Model has a tough, easy-to-grasp, molded handle and a metal-reinforced crank handle for long life.
