Product Overview
The Douglas Aluminum Ground Sleeve is a 24-inch-long square sleeve made from robust aluminum construction, designed to be permanently installed in the ground to accept 4-inch square posts. It provides a stable, in-ground anchoring point for compatible net systems.
This ground sleeve is included as standard equipment with the Douglas 4 in. SQ Aluminum Adjustable Net System and the In-line Basketball Aluminum Net System, making it a suitable replacement or spare part for those setups. It is sold individually, so quantity should match the number of posts being installed.
For installations where posts need to be removed for off-season storage, Douglas recommends pairing this ground sleeve with T-Plugs to keep the sleeve free of debris and protected when not in use.
