The Heavy Duty Outdoor Pickleball Portable Net System by Douglas is a great solution when permanent installation isn't an option or isn't desired. The 3.0 portable pickleball net system can be used either indoors or outdoors. The heavy-duty non-scuff swivel caster allows for smooth and easy mobility. The transporter brackets flip up and out of the way while the unit is in play. The portable Pickleball net post and base frame frame are finished with a black baked-on polyester powder coat to resist rust and increase durability. The 3" square net post is constructed from heavy-duty 11-gauge steel. The base frame is also constructed of 11-gauge 3" square steel and 3-1/2" square 3/16" heavy-wall steel.
