Nail-on extender insulator that fastens electrified wire to wooden fence posts while maintaining a 5" standoff distance. Prevents energy loss through the post for more effective electric fencing. Yellow color provides high visibility along the fence line.

• Extends wire 5" from wooden post for proper standoff
• Compatible with 9-22 gauge high-tensile steel or aluminum wire
• Works with all polywire and polyrope up to 1/4" diameter
• UV-stabilized polyethylene construction for outdoor durability
• High-visibility yellow color
• Nails included for easy installation
• 25 insulators per bag

Ideal for perimeter fencing, livestock containment, and predator control. Proper insulator standoff helps maintain consistent voltage along the entire fence line.
