Trigon Sports 4' Ground Sleeves for 20' Foul Poles

These 4-foot in-ground pole sleeves are designed to provide secure and dependable support for 20-foot baseball and softball foul poles. With a 48-inch deep installation design, the sleeves create a stable foundation that helps maintain proper pole alignment and structural integrity during regular gameplay, seasonal weather changes, and long-term outdoor use. Ideal for schools, parks, recreation facilities, and competitive athletic fields, the sleeves are engineered to support reliable foul pole installation for year-round field operations.

Constructed from heavy-duty materials, the pole sleeves help reduce shifting, movement, and wear at the base of the foul pole over time. Designed for compatibility with standard 20-foot foul poles, they can be installed during new field construction or facility upgrades for a clean and professional setup. The removable sleeve design also allows poles to be lifted out easily for field maintenance, offseason storage, or replacement without disturbing the permanent foundation. Built for durability and practical field management, these ground sleeves provide a reliable installation solution for maintaining properly aligned foul poles throughout the season.
