Model: 4mm x 30m EASY GRIP: The case is equipped with a handle and an adjustable grip around the spool, giving you a firm and stable hold when removing the tape from the box. The straps wrap directly into the housing without you having to interfere with the fastening straps.

LONG LIFESPAN: Uses steel wire material, durable, corrosion-resistant, and with high spring, wire pulling is more convenient and has a longer lifespan. WIDE APPLICATION: Ideal for wrapping/threading or pulling cables and wires through or behind ceilings, walls/drywall, pipes, PVC, air ducts, conduits, under carpets or insulation, and more for indoor and outdoor electrical installations.
