Postsaver Rot Protector Sleeve for 75mm - 100mm Square Fence Posts

Postsaver Rot Protector Sleeve designed for 75mm-100mm square fence posts. Heat-shrink post protection sleeve engineered to prevent ground-line rot and decay in timber fence posts. Manufactured from a dual-layer barrier system combining a thermoplastic outer layer and bitumen-based inner liner, the sleeve creates a watertight and airtight seal at the critical ground-contact zone where moisture and oxygen combine to cause decay. When heat applied, the sleeve shrinks tightly around the post surface and bonds permanently, providing long-term protection against rot, fungi, and bacterial degradation. Compatible with both treated and untreated timber posts, it significantly extends the service life of fencing, gate, and decking structures. The 75mm-100mm size fits standard square posts, providing complete ground-line coverage and protection in all soil conditions.
