The Tapco M2X Measuring Gauge is the first innovative tool that will work universally with any Tapco (except for the Pro 50 and Windy Special) siding brake. Tapco M2X Measuring Gauge is a time saving system that will allow a contractor to measure right on the brake, instead of using a tape measure. This gauge includes on board measuring tape and two movable brackets with corresponding measurement markings for more precise measuring and efficient bending.
