The black body houses a semicircular supporting core and accepts wire, poly wire or poly rope up to 5 mm for versatile fence planning.

Where To Use
Well suited to permanent wood post fences on cattle ranches, horse properties and deer enclosures where lines stay taut for years. The knurled thread is especially useful on weathered posts that offer less grip to smooth screws.
Installation Tips
Turn the insulator clockwise with steady pressure so the knurled teeth cut cleanly into the wood. Check tightness after the first tensioning pass and re-tighten if needed. Volume buyers can request alternative colors, packing sizes and shipping marks.
