The Irwin Professional Pocket Tape has a high-grade nylon coated steel blade with double side printing in metric and imperial graduations. The nylon coating offers up to twice the life of a standard coated blade. The magnetic hook is affixed with two rivets for added strength and the blade itself can stand out to a very impressive 1.8 metres, handy when working alone or taking long measurements. The Pro Touch ergonomic case provides a soft, comfortable grip and Fast Lock. The locking mechanism helps to stop and grip the tape far quicker than other models.
