These markings allow you to accurately measure the depth of conduit runs and determine the amount of tape left to pay out.PRODUCT FEATURES:• High strength spring steel fish tapes are stiff for long runs and are great for heavy duty wire pulls.• Laser etched markings in 1' (0.3 m) increments allow you to more accurately measure the depth of conduit runs and determine the amount of tape left to pay out.• Polypropylene case and handle offer the maximum in impact resistance.• Full grip-style handle gives you a firm, steady grip as you pull tape from the case.• Raised fingergrips transfer 100% of the winding power from your hand and fingers.• Unique sloped handle optimizes hand position for quick hand-over-hand rewinds.• Patents: D574,277; 8,212,178; 8,168,921; 8,164,025.
