Frienda electric fence screw-in insulators 100-pack, yellow UV-resistant plastic for round & T-posts

Frienda 100 pcs electric fence screw-in insulators are durable, UV-resistant plastic fittings designed to secure electric wire or polyrope to round and T-posts safely and reliably.

These screw-in round post insulators come in a bulk 100-count pack and are shaped to work with 1/4"–9/16" wooden round posts and 5/8" fiberglass T-posts. Built from weather-resistant plastic with a hex-screw mounting system, they keep electrified wire and rope away from the post to reduce grounding and chafing while letting strands slide when needed. The high-visibility yellow helps you see fence lines in daylight, and the set is intended for farms, ranches, pet enclosures, gardens, and other outdoor perimeter projects.

How do these insulators attach to posts?

Each unit uses a detachable hex screw that threads into round wood or fiberglass posts. You place the insulator body on the post, insert and tighten the hex screw from behind, and then run your wire or polyrope through the opening.

• Hexagonal screw included for secure mounting
• Fits 1/4"–9/16" round wooden posts and 5/8" fiberglass T-posts
• Design allows insulator to slide or be fixed along the post

Will these hold up outdoors through seasons?

The insulators are molded from robust plastic formulated to resist UV degradation, moisture and temperature changes. They’re meant to remain dimensionally stable and keep insulating performance over repeated outdoor exposure.

• UV-resistant construction reduces fading and brittleness
• Weather-resistant material stands up to rain and sun
• Non-deforming shape maintains wire clearance from posts

What types of fence wire and setups work with these?

The opening and profile accommodate electric wire, polywire, polyrope, and small multiple-strand combinations. Their size and shape let you run single or several strands while minimizing contact with the post that could short or wear wiring.

• Compatible with electric wire, polyrope and polywire
• Large hole supports multiple strands when required
• Suitable for livestock, pet containment, garden and perimeter fences

How many insulators are included and where are they best used?

• 100-piece bulk pack for wide coverage
• Well-suited for farm, ranch, pet fence, and garden protection
