The optimized housing and handle design decreases payout effort and reduces binding.The large handle allows for a firm, steady grip as you pull the tape from the housing. The tape features laser-etched descending markings placed at every foot. These markings allow you to accurately measure the depth of conduit runs and determine the amount of tape left to pay out.
