Reelpower Industrial  Model 1704 measurer is designed to measure heavy and large diameter material such as Wire Rope and large diameter Cable. The pivot arms and springs keep the measuring roller tightly clamped against the cable to ensure accurate measurement. The heavy top and bottom rollers make it easy to pull material from reel racks. A fairlead for improved accuracy when measuring material under 1/2” diameter is provided. When not in use, the fairlead swings away in a second’s time.
