Some fence applications call for a little extra holding power. The Double U Insulator uses a dual-staple design to attach securely to wood posts, giving your electric fence wire a firm, stable mount that resists movement even under the pressure of tensioned wire or livestock contact.

The double-U configuration distributes the holding force across two staple points, reducing the chance of the insulator pulling free over time. It's a reliable choice for permanent wood post fence lines where you need insulators that stay put season after season without constant maintenance.

Built from UV-stabilized polymer, these insulators hold up in all weather conditions without cracking or fading. Sold in packs of 10.

Features

Dual-Staple Design
Two-point attachment to wood posts provides a more secure hold than single-staple insulators, resisting pull-out under wire tension.

Stable Wire Position
Keeps electric fence wire firmly in place and properly isolated from the post to prevent shorts and voltage loss.

UV-Stabilized Construction
Durable polymer resists sun damage and weathering for long-term outdoor performance on permanent fence lines.

Low Maintenance
Secure double-U attachment reduces the need for re-stapling or insulator replacement over time.

Versatile Wire Compatibility
Suitable for polywire, polybraid, polytape, and standard electric fence wire.
