Flat Back Tube Insulator - Finned 4" Box of 2500
Tube insulators are the lowest cost insulator option for high-tensile wire fences. The flat-back insulator is designed to allow a staple to anchor into the fins to prevent it from sliding.
It is installed by sliding the appropriate number (corresponding to the number of posts) onto the end of the wire. Push the group of insulators down the wire and each tube as you proceed down the line. Be sure to staple in far enough so the tube cannot easily slide away from the post, but not so hard that it restricts wire movement. 2500 per pack
