Without a proper Earth System your energizer will not perform. Earthing ensures that the current can flow back to the energiser as soon as an animal touches the fence. No earthing means No current on the fence - which is essential to a good fence. If you have any queries please give our team a call to discuss earthing further, we would be delighted to assist.

Always use galvanised earth stakes.
Pack of 3 number 1m Long Galvanised earth stakes.
Battery Energizers: Earth Stake length 1m c/w clamp
Mains Energizers: (advice) Earth Stake length 2m c/w clamp.
