Used with 4 in. galvanized CAT64 J-hook fasteners, which are UL Listed and designed to support up to 300 UTP four-pair cables, the pulley allows a single person to install the cable. The cost-effective system complies with the TIA standard that requires minimizing the pull force on the cable. It also maintains proper bend radius and protects the cable during installation. Available with a kit including a J-hook, pin, wheel, and retainer, the pulley accommodates up to 40 four-pair cables. The system comes read to nail or screw directly to the structure or it can be assembled to any other CADDY fastener for easy attachment to beams, decking, C&Z purlins, drop wires, and rods. When the job is complete, the pulley and pin assembly can be removed, leaving the J-hook as a cable support. The pulley components can be reused on any current design CAT64 J-hook.
