I attached this to the front edge of my new workbench. When I need to cut wires to a specific length, I don't have to grab a tape measure and line it up. There is extra unmarked tape on the O end that I wrapped around the left edge of the table, it should reduce fraying. It was long enough to the right end. It contains a metric that I use when calculating lengths. still happy The previous work area had a less durable strap and it broke over time. Qui vivra faith.
