BlackBoot Steel Post Insulators | Steel Post Insulators | 50 Pack
BlackBoot Steel Post Insulators are a simple and reliable way to attach electric fence wire to steel fence posts. Designed around the 2.5mm wire most commonly used in permanent electric fencing, they provide a secure insulated fixing point while helping maintain good fence performance along the line.
These insulators are made to work with McNamara Fencing BlackBoot Steel Fence Posts, making them a practical choice for customers building or extending electric fencing systems with steel line posts. They are quick to fit using the included split pins, allowing fast installation through the post holes and helping reduce time spent on fence setup.
Made from durable UV-resistant plastic, they are built for outdoor use and are suitable for long-term electric fencing applications. The wire sits securely in place, and the insulator helps separate the live conductor from the steel post to reduce unwanted power loss.
For farmers and landowners using steel fence posts, choosing the right insulator matters. A good section insulator helps keep the fence live, supports a tidy wire line and makes installation more straightforward. These insulators are a cost-effective option for permanent and semi-permanent electric fencing where durability and ease of fitting are both important.
Each pack includes 50 insulators and 50 fastening split pins, giving you everything needed for installation. They are well suited to farm fencing, paddock divisions, grazing systems and general livestock control on steel post fencing layouts.
