✓ Authorized Douglas Dealer — ships brand-new with the full factory warranty

The Douglas GS-36SQ Steel Ground Sleeves are built to permanently house 3 in. square volleyball posts in the ground, providing a stable base for sand volleyball court setups. Each sleeve measures 36 in. in length and is constructed from steel for durability in outdoor, in-ground installations.

This set includes collars specifically designed for sand volleyball installation, and the sleeves are sold in pairs to accommodate both post locations on a standard court setup. The total shipping weight for the pair is 52.000 lbs.

Finished in black, these ground sleeves are intended to be installed flush with the playing surface, allowing posts to be inserted and removed as needed while keeping the court surface clear when posts are not in use.
