A Gripple is used to connect two ends of our 12 gauge monofilament wire together. This Gripple can fit 2.00mm-3.25mm (0.0787 inches-0.128 inches) wire or monofilament. It has a tension strength of 880 lbs. Simply place 12 ga. monofilament wire into the holes on either side of the Gripple. The 12 ga. Gripple tool will automatically grab and secure the monofilament wire ends without releasing them. Deerbusters recommends using our Gripple tightening tool to tighten the monofilament wire using the ratcheting action of the Gripple.
