The Irwin Standard Pocket Tape has a high-grade acrylic coated steel blade with both metric and imperial graduations. The acrylic coating helps to reduce reflection when reading. The traditional metallic hook is affixed with 2 rivets for added strength and the blade itself can stand-out to a very impressive length*, handy when working alone or taking long measurements. The ProTouch™ ergonomic case provides a soft, comfortable grip and the blade can be kept firmly in place by the conventional slide blade locking device. A great all-round tape measure suitable for countless applications. *Blade stand-out length varies, depending on overall length of blade.
