Fish tape or wire-puller has been designed to put an electric wire into a conduit easily and is a tool that, if a electrical worker pushes the wire-puller into the conduit and connects the wire with the front terminal hole of the wire-puller coming out of the other side of the conduit before pulling the wire-puller, makes the wire pass through the inside of the conduit. Using a steel wire, instead of the fish tapes, to put the electric wire into the conduit in the past was a hard work, and the wire got caught frequently inside the conduit. On the contrary, our fish tape or wire-puller uses gently-bent, special PVC materials, so working is not hard, and the wire, when pulled by the hand, can be inserted into the conduit without difficulty. In particular, our wire-puller has perfect insulation, which is a basic condition of electrical work tools, and thus makes workers work securely and displays a better performance in distant electric works (fish tapes with a length of 10M, 15M,20M, 30M,40M, 50M, and 100M, and with other special length available) Moving Picture : http://youtu.be/ynoKJwAHWgA
