Thunderbird Wood Post Screw Ring Insulator 200mm
The Thunderbird Wood Post Screw Ring Insulator 200mm is a quality fence insulator for timber post electric fencing. This screw-in insulator keeps electric fence wire 200mm clear of the post, preventing current leakage and maintaining fence voltage. Electric fencing is one of the most cost-effective livestock management solutions available.
This insulator mounts securely to timber or steel posts and holds the electric fence wire or tape in position while maintaining the electrical separation required for effective shock delivery. Good quality insulators prevent energy leakage, keeping your fence energiser working efficiently and your fence shock strength consistent.

Why Choose a 200mm Offset Insulator?
First and foremost, the 200mm offset design of this fence insulator keeps live wire well clear of the timber post, preventing current leakage through damp wood. Furthermore, the screw-in design makes installation quick and secure — a single tool is all that is needed. As a result, this insulator delivers reliable insulation performance in Australian conditions across all seasons. In addition, the white colour provides visibility for inspection and maintenance. According to the Australian Government Department of Agriculture, proper insulation is critical for maintaining effective fence voltage for livestock containment.
Tips for Installing Fence Insulators
Before screwing in, drill a pilot hole in the timber post to prevent splitting. Then, screw the fence insulator firmly until the base seats flush against the post. In addition, ensure wire clips into the ring correctly and is not kinked. Finally, inspect all fence insulators after heavy rain and replace any that are cracked or damaged.
