This metal electric fence post has been designed specifically for use around ponds to protect expensive koi and other fish from herons and cormorants but is also being used with great success around other parts of the garden, for example on top of panel fences to keep pets in and/or out.
The pond posts are 200mm long (from the bend), 5.5mm in diameter and powder coated black metal. There are two 3-4mm fixing holes on the flat plate for you to screw or nail the post in place; use a red raw-plug if fixing into stone. Each pond post weighs 50.5g.
Pond posts are sold in packs of 5 with 15 insulators
