Everhard’s MM21110 Stand-Up Membrane Slitter lets users cut membrane standing up instead of on hands and knees, slicing through membrane accurately and easily. The slitter cuts straight or curved lines through membrane. Its unique design helps prevent accidental punctures, and the slitter won’t damage any materials under the membrane. With two wheels for balance and a yellow pointer, the slitter's design helps users follow scribed lines. It uses replaceable, standard utility blades inside a removable blade cartridge. The product is made in the United States. For more information, visit www.everhardroofingtools.com.
