JouleShield™ Wood Post Pinlock Insulator
Product Details
Heavy-duty pinlock insulator from Strainrite Fencing Systems for securely holding high-tensile wire and low-tension electric fence conductors.
Key features:
- Pinlock design works well as a line insulator and simplifies adjustments and routine repairs
- Large surface area and shielding help reduce power leakage and maintain fence voltage in all weather conditions
- UV-stabilized polymer for long-term durability
A practical choice for straight fence runs where easy adjustment and consistent performance matter.

Common Questions
- Pinlock vs. Claw — What’s the difference?
- Pinlock insulators are generally easier to work with. The wire conductor can be inserted or removed quickly by pulling the pin, even with some tension on the line. This allows for faster, simpler adjustments and repairs.
Claw-style insulators trade that convenience for durability. With no small pin to break, they offer a more rugged hold and are better suited for high-stress areas where long-term strength matters more than quick adjustments.

Exactly what I was looking for to have electric fence to keep deer out of gardens. Easy to order, timely delivery and a product I had difficulty finding in stores.

There are really nice heavy duty plastic. Much sturdier than ones I have purchased locally from the feed store.
