The First Team Slam III is built around a one-piece 4" square vertical pole with a minimum 11 gauge wall thickness, designed to be buried 36" in concrete, and finished with a watertight vinyl cap to seal out moisture.

Adjustable extension arms made of dual 2"x2" 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 from 10' down to 7' in six inch increments via a removable pin and pin bracket, aided by two counterbalancing springs for one-person adjustment.

The backboard is constructed of 1/2" thick acrylic with bright white screening and a clear anodized aluminum "L" type extrusion frame, measuring approximately 54" wide by 36" high, paired with a flexible, institutional-quality steel rim finished in orange powdercoat. The entire system weighs approximately 284# and the pole, backboard, and standard rim carry a Lifetime Limited Warranty.
