Pioneers in permanent electric fencing. Designed by a farmer for farmers. Douglas Beattie has been designing, manufacturing and marketing the Beattie insulator range of electric fence products for 38 years. Beattie insulators have been widely used in New Zealand and Australia, having a major share of the permanent fence insulator market dating back to the early 1960's, most of which are still in use today. Most of Beattie insulators are moulded from virgin black low density polyethylene, a material we have used in the field since 1960, therefore we have total confidence in backing our 20 year guarantee.
