PostSaver® sleeves are designed to protect wood fence posts from ground-line rot, the most common failure point in fencing.
Using a heat-activated bitumen barrier, the sleeve shrinks tightly around the post to isolate the critical soil-line zone where moisture, oxygen, and soil organisms cause wood decay.
When installed correctly, PostSaver® sleeves provide up to 20 years of protection against ground-line rot.

PostSaver® sleeves are designed to isolate the ground-contact zone of a fence post.
This critical area is where:
• moisture accumulates
• oxygen is present
• soil microorganisms attack wood fibers
By creating a protective barrier around this section of the post, the sleeve helps slow the decay process and extend the life of wood posts used in fencing, landscaping, and agricultural applications.
Proven Ground-Line Protection
Fence posts most often fail at the soil line. PostSaver® sleeves create a barrier at this vulnerable zone to help reduce decay.
Designed for Contractors
Used widely in fencing, agricultural installations, and landscaping projects where ground-contact protection is required.
Compatible with Multiple Post Types
Sleeves can be used on:
• wood fence posts
• metal posts
• round or square posts
Long-Term Protection
When installed according to guidelines, PostSaver® sleeves provide approximately 20 years of ground-line protection.
Two installation options are available depending on your project.
Pro-Sleeve
A full sleeve that covers the ground-contact portion of the post before installation.
Pro-Wrap
A wrap-style system designed for retrofit applications or installations where sliding a full sleeve over the post is not practical.
Both options are designed to isolate the soil-line zone where decay typically begins.
Fence Armor now offers RotGuard™ ground-line protection, designed for modern installations.
RotGuard™ features:
• Self-adhesive installation
• No torch or heat required
• Flexible SBS polymer membrane
• Made in USA
• 25-year limited warranty
