This is an exceptionally high quality 72" x 42" steel backboard for indoor and outdoor use. The finish is durable powder coat with red shooting square and parameter boarder. The heavy 11 gauge steel surface is reinforced from the back side with an evenly spaced ribbed design which eliminates any vibration and undesirable noise characterized by other steel backboards of lesser quality. All weld beads are minimum one inch in length (no spot welding). All seams are sealed and painted to help prevent rust streaking on the back side. Attachment slots allow this board to be used for a standard mount or a fan shape conversion (mounting hardware included). Parameter thickness of the board permits the use of standard high grade urethane bolt on pads to be used (see below for selection). Meets all regulation requirements for NCAA and National High School Federation. Lifetime warranty on structural design. Shipping weight: 208 lbs - Freight Only.
