Square fence post ground line sleeve – pack of 10

Bitumen-lined protective sleeve for square fence posts, engineered to prevent ground line rot and extend post service life.

The ground line zone—where timber meets soil—is where fence posts fail fastest due to moisture, fungal decay and bacterial attack. These sleeves create a watertight, airtight seal around the vulnerable ground line section, blocking the conditions that cause premature rot in timber posts.
