Strainrite T-Post Insulators — 300 Pack

300 T-Post Insulators — Bulk Supply for Steel Post Fence Lines

Steel T-posts conduct, which means every wire that touches one is a voltage leak waiting to happen. Strainrite T-Post Insulators hold the hot wire clear of the post with a pinlock design that snaps on and stays put, keeping the charge in the fence where it belongs instead of draining into the ground through the steel.

This 300-count supply covers a full run of steel post fence without a resupply trip mid-job. Moulded from UV-stabilised heavy-duty plastic so they hold up through seasons of sun exposure rather than going brittle and cracking off the post after a summer. They fix to steel T-posts by snapping on, and they screw directly into timber where the line changes post type.

Features

Pinlock Design
Locks onto the post and holds the wire in position — no slipping down the post, no popping off under wire tension.

UV-Stabilised Heavy-Duty Plastic
Built to resist sun degradation, so the insulator body stays tough instead of turning brittle and failing after a season in the open.

Snap On or Screw In
Snaps onto steel T-posts and screws into timber posts — one insulator handles both post types on mixed fence lines.

Bulk 300 Count
Enough insulators to run a full steel post fence line in one go — sized for contractors and full-property builds.

Keeps the Fence Hot
Holds the electrified wire clear of conductive steel, preventing the voltage loss that kills an electric fence's effectiveness.
