The Slam II Basketball System features a one-piece 4" square vertical pole with a minimum 11 gauge wall thickness, designed to be buried 36" in concrete, and topped with a watertight vinyl cap to seal out moisture.

Adjustable extension arms, built from dual 2" x 2" tubing, provide a minimum 24" distance from the front of the post to the face of the backboard at a 10' playing height, and allow rim height adjustment in six-inch increments from 10' down to 7' via a removable pin and pin bracket. Two springs in the extension assembly counteract the weight of the backboard and rim for easy one-person adjustments, and the rim mounts directly to the extension arm through the backboard to reduce stress on the backboard.

The backboard is constructed of 3/8" thick acrylic with bright white screening and a clear anodized aluminum "L" type extrusion frame, measuring approximately 48" wide and 36" high. The flexible, institutional-quality rim has an official 5/8" diameter ring with a standard 18" I.D. opening, an orange powder coated finish, and a heavy-duty nylon net. The pole, backboard, and standard rim carry a Lifetime Limited Warranty, and the entire system weighs approximately 195 pounds.
