The quick and easy way to connect and tension wire fencing and trellis wires. The Gripple wire joiner lies at the core of the system. In its interior each wire moves in only one direction. The fencing wire is placed in the patented wire tensioner from the right and the left. The Tensioning Tool uses lever action to tension the wire. To joint trellis wire to an anchoring post the wire is pulled through the Gripple, a loop of wire is laid around the post and pushed back through the other side of the Gripple. Additional tension can be applied to the wire as often as needed by the Gripple pincers.
