ABSTRACT:
A bumper indicator is disclosed which is adapted to be used on the tape rule of a measuring tool. The bumper indicator is a one piece resilient member having front and rear surfaces and a transverse slit whose configuration is selected to be generally complimentary to the cross sectional configuration of the tape rule on which it is mounted, thereby to frictionally engage and slidably receive the tape rule. The bumper has top and bottom edges and the rear surface of the bumper facing the casing for the tape measure is chamfered from a position below the slit to the bottom edge. The bumper serves to cushion recoil of the tape, as well as to provide an indicator along the tape when it is extended to facilitate repetitive measurements.
