The Margo Pin Lock Wrap-Around Insulator (often referred to as a “Corner Collar”) is a heavy-duty, essential component for any high-tensile electric fencing system. Designed specifically for corners, end posts, and termination points, this insulator provides a massive 3.5-inch flat insulating shield that sits between the wire and the post.

Unlike standard insulators that can allow wires to “bite” into the post or arc during wet weather, the Wrap-Around design creates a total non-conductive barrier. It ensures that even under the  tension required for bear deterrence or large livestock containment, your wire remains fully insulated and your voltage stays high.

🔑 Key Features & Benefits

• 3.5″ Protective Post Shield: The extra-wide flat flange acts as a “collar” behind the wire, preventing it from touching or cutting into wood and steel posts at high-pressure angles.

• Pin Lock Convenience: The signature pin-lock system allows for “no-tool” wire installation and maintenance. Quickly drop wires for seasonal adjustments or repairs without removing the insulator.

• High-Strain Engineering: Built to handle the massive directional pull of corner assemblies and gate ends—the most common points for fence failure.

• Multi-Surface Compatibility: Designed for wood posts (nails/screws) and flat steel posts/square tubing (self-tapping screws).

• All-Climate Resilience: Molded from UV-stabilized, high-density polypropylene. This industrial-grade material won’t crack in sub-zero northern winters or degrade in intense summer heat.

🌍 Versatile Applications: High-Performance Protection

• 🐻 Bear & Wildlife Exclusion: A critical component for bear deterrent systems. The wrap-around shield ensures that pressure from a large animal won’t ground out the wire against the post, maintaining the full repelling shock.

• 🚜 Agricultural & Livestock: The gold standard for permanent cattle, bison, and horse perimeters. It eliminates “ghost shorts” at corners, which are often the hardest faults to track down.

• 🏗 Industrial & Security: Provides a reliable, long-term insulating layer for energized security fences around equipment yards, infrastructure, and high-value storage.

🛠 Installation Tip

For maximum effectiveness, place the Wrap-Around Insulator at every corner and end post. Ensure the 3.5″ flange is positioned directly between the wire and the post surface to provide the necessary “wrap-around” insulation barrier.
