These connection sleeves are used to terminate a run of 8 gauge monofilament line at the corner or end of our deer fencing systems. The connections sleeves come in packs of 25. Thread the the monofilament wire through one side of the connection sleeve. Wrap the monofilament line around the corner or end post, and thread the end of the monofilament line through the remaining hole of the connection sleeve. Use our sleeve crimping tool to crimp down on the connection sleeve to secure the monofilament line in place.
