Utilities worldwide are increasingly specifying Rot-Guard ground-line protection as a proven way to maximise pole service life. To help pole yards meet this growing demand efficiently, Polesaver has developed a high-power electric shrink system designed specifically for indoor production environments.
The result is a fast, safe and consistent way to apply Rot-Guard at scale.
Industrial Shrink Technology for Pole Production
The ShrinkMaster™ is a rail-mounted, electric shrink machine designed for high-volume pole yard operations.
Powered by a 28kW electric heating system, the machine delivers consistent heat output for reliable shrink installation without the need for naked flames.
Installed within the finishing area, it enables pole yards to integrate Rot-Guard application directly into production, removing the need for in-field installation using gas blow torches.
SHRINKMASTER™ Key Benefits
Indoor Application
The system is designed for indoor use within pole yard production areas, creating a controlled and safe installation environment.
No Naked Flame
Unlike application in the field, the machine operates entirely electrically, removing the need for blow torches or gas equipment.
High-Volume Processing
The rail-mounted design enables efficient batch processing, helping pole yards scale Rot-Guard installation as demand grows.
Consistent Application Quality
Controlled electric heat ensures uniform shrink performance and reliable ground-line protection.
Production Efficiency
Applying Rot-Guard in the yard eliminates the need for in-field installation, which appeals to utilities.
Premium Pole Offering
Pole yards can supply poles fully protected at ground line, allowing them to offer a higher-value, premium product to utilities.

Why Choose Rot-Guard?
Decay Protection
Rot-Guard
Rot-Guard sleeves form a dual-layer barrier around the ground-line portion of the pole, preventing moisture + decay-causing factors from entering the wood and compromising its integrity. When used in combination with copper-based preservatives, this solution ensures pole strength is maintained over time for improved safety and grid resilience.
Polesaver manufactures and supplies guaranteed products that are proven to maximise utility pole lifespan. With millions of Rot-Guard sleeves supplied to date, our patented ground-line barrier sleeves have been proven in volume use since 1994.
*Polesaver uses long term independent test data on the effectiveness of barrier sleeves and fire protection fabric to reach all the conclusions given on this website (test data available on request). Based on this data, Polesaver believes longer life, maintenance of strength over time, improved safety and reliability, extended inspection periods and reduced maintenance requirements are reasonable claims. This is subject to Polesaver products being correctly applied as per our instructions and used on correctly preservative treated (for long term in-ground use - Use Class 4 or higher) wooden utility poles that are free of decay at the time of sleeve application. The claims made, real or implied are not warranties. It is the responsibility of the user to evaluate and satisfy themselves that the performance of the product meets their specific safety, reliability, extended inspection, repair and any other performance or cost-benefit criteria before using Polesaver sleeves or fire protection fabric.
