The P37 Insulator is a heavy-duty reinforced screw-in ring insulator designed for secure attachment to any wooden post. Suitable for polywire, galvanized wire, and rope up to 7mm. It is also compatible with the insulator speed chuck.

The primary role of an insulator is to securely hold the fence line, preventing power leakage from the post to the ground. A well-designed insulator ensures the line is held firmly, minimizing wear on the tape, rope, or wire caused by wind and weather, and allowing the line to pass through smoothly without obstruction from sharp edges.
