Product Information

Full details

The Fenceman Insulator Screw In (21cm) is an essential tool for farmers, livestock owners, and property managers who need to mount electric fencing to permanent posts. Designed to maintain the integrity of your perimeter, these insulators ensure that the electrical charge remains within the fence line without leaking into the support structures. While these 21cm units provide excellent standoff distance from wooden posts, they are intended specifically for screw-in applications and may not be suitable for metal or T-post setups without modification.

Extended Product Information

FAQs

Can I use these on metal posts?

No, these are designed specifically with threads for wooden posts and will not fit standard metal fencing posts.

Do I need special tools to install them?

No tools are required for softwoods, though a power drill with a small pilot bit is recommended for hardwoods.

Are these suitable for high-tensile steel wire?

They are primarily designed for polywire and electric rope. High-tensile steel may cause wear on the plastic over time.

What is the total length of the unit?

The insulator has a standoff length of 21cm from the post.

How many come in a pack?

This product comes in a convenient pack of 10 units.

Will these degrade in the sun?

They are made of weather-resistant, durable materials designed to withstand outdoor exposure, though they should be inspected periodically.

Troubleshooting

Insulator is loose in the wood

Remove the insulator, fill the hole with a wood plug or outdoor-grade filler, and reinstall in a slightly different position.

Fence is losing power at the post

Inspect the insulator for cracks or moisture buildup. If the surface is dirty, wipe it clean to prevent tracking.

Pros and Cons

Pros

  • Simple, tool-free installation into wood
  • Effective prevention of electrical shorts to posts
  • Durable construction suitable for outdoor longevity
  • Provides significant clearance from support fixtures

Cons

  • Requires pre-drilling in very dense hardwoods
  • Not compatible with metal posts
  • Limited to screw-in wood mounting applications only

Setup, Compatibility & Care

To install the insulators, simply align the tip against the wooden post and rotate the body clockwise until the threaded section is fully seated. For hardwoods or older, dried-out posts, it is recommended to drill a small pilot hole first to prevent the post from splitting.

Compatibility is strictly limited to wooden post surfaces. To maintain the life of your insulators, inspect them annually for UV degradation or signs of cracking. If an insulator becomes brittle, replace it immediately to ensure the fence maintains its full voltage rating throughout the season.
