Zareba IW5XNY-Z Nail-On 5-Inch Extender Insulator – 25 Pack

Enhance your fence with the Zareba IW5XNY-Z Nail-On 5-Inch Extender Insulator

Designed to secure electrified wire to wooden posts while keeping the wire offset from the surface, this extender helps maintain tension and reduces wear at the post connection. By moving the wire 5 inches away from the post, you can create a clearer path for the wire and simplify inspection and adjustments over time.

Built for versatile fencing needs, this extender supports a wide range of conductors and installation scenarios. It is suitable for common wire gauges and materials, making it a flexible choice for evolving fence setups on a farm, garden, or rural property.

What it does

• Fastens electrified wire to wooden posts without energy loss at the post
• Extends the wire 5 inches from the wooden post
• For 9 gauge through 22 gauge high-tensile steel wire and aluminum wire, all polywire (regular and heavy duty), and polyrope up to 1/4 inch diameter

Practical use cases

Ideal for fence lines around barns, gardens, and animal enclosures where you want a clean, aligned wire path. The 5-inch offset helps with wire tensioning, post cleaning, and ease of routine checks on large or multi-section fences.
