JVA 4mm Bobbin
A UV-stabilised 4mm security insulator for electrifying gates and metal structures
The JVA 4mm Bobbin is a small, UV-stabilised insulator that holds electric fence wire clear of a metal surface, so the current stays in the wire instead of leaking into the structure. It is a common choice for electrifying a gate or a wall-top fence line.
It fixes with a Tex screw, so you can attach it straight to square tube or flat bar without special fittings. Once the bobbins are in place, the wire runs along them, held clear of the metal.
Key features
- UV-stabilised. It is built to stand up to long-term sun exposure on outdoor installations.
- 4mm security insulator. It is sized for security fencing applications.
- Simple Tex screw fixing. You can attach it directly to square tube or flat bar without special fittings.
- Keeps the current in the wire. It holds the wire clear of the metal so the structure doesn’t become live or earth the fence.
- Black finish.
Ideal for
- Electrifying gates
- Wall-top fence lines
- Square tube or flat bar structures
- Security fencing installations
