Inside every Gripple Wire Joiner & Tensioner are high precision gear-toothed rollers. These rollers grip each wire allowing it to move in one direction only. The moment any load is applied, the rollers "bite" into the wire - locking it into place. The geared Tensioning Tool makes for quick and easy tensioning.
Gripples work great on new fencing ~ but are especially useful and quick on repairing and fix'n old or damaged fence. As with "old rusty barbed wire" - that may break when you try to bend it and knot it.
The Large Gripple Plus works on 7.5-10 gauge smooth wire. The Gripple T-Clip is recommended to secure woven wire fence around end posts with using a knot or stapling the wire.
