The GMP Tools Mid-Assist Fiber Optic Capstan features a 25-inch diameter and a slip clutch torque limiter factory-set to 600 pounds-force, enabling controlled pulling tension to protect fiber optic cables during installation. Designed for use as end pullers or mid-assist booster pullers, these capstans facilitate long, straight-through, splice-free fiber optic cable pulls and are compatible with cable blowers for longer cable placements without splicing. An option with a steel shaft and no torque limiter handles loads up to 1500 pounds for no-slip applications. This heavy-duty tool weighs 80 pounds and is manufactured in the United States, making it suitable for demanding pipe and conduit operations involving HDPE couplers and sweeps.
