18-Inch Hole Sleeve

The 18" Hole Sleeve is designed for fixed-axle utility trailers and campers that sit higher off the ice when converted into fish houses. The extra depth keeps cold air from rushing up through your fishing holes, helping your house stay warmer and reducing freeze-up.

These sleeves rest securely inside the Catch Cover ring, creating a clean seal while still allowing airflow to minimize ice skimming over holes. Lightweight, durable, and easy to store, the 18" Hole Sleeve includes molded 1" trim lines so you can customize the height to fit your floor system perfectly.

With a universal fit, it works with all brands of fish-house hole covers.
