The safety gripper is best used when using a conibear trap or any body gripping kill traps. Once body traps are set, this item allows you to handle the trap safely until it is positioned. Use with the 110d, 160d, 220d, and the 330d. This item is highly recommended for people not familiar with these traps or when they are to be positioned in difficult or low visibility areas and it fits in your pocket! At this low price it definitely pays to be safe.
