Built best to be the best! Over twenty steps go into the construction of each backboard panel. Pre-fabricated panel concept allows virtually an unlimited size and/or placement capability for any facility or application. Each panel is 4 feet wide, 8 or 10 feet high and weighs 80 to 150 pounds. The backboards are ready for play when the multiple, pre-fabricated, completely finished, green fiberglass interlocking panels are affixed to tennis court fence posts or wall by the Bakko assembly kit in a tight, unitized, side-by-side construction. Kits come in traditional flat, single and double curved styles. All kits are complete. Minimum adequate size is 8' high by 12' wide backboard (3 panels). Attaches to two tennis court fence posts which, on most tennis courts, are spaced 10' apart. Typically 16' wide (4 panels) and 20' wide (5 panels) backboards require 3 tennis fence post for attachment. A 16' backboard, if post are standard, expose more channel and hardware. It is not as aesthetically pleasing. Typically 3 or 5 panel models have minimal hardware and channel exposure. If post are 8' apart a 16' wide backboard can be elegant. 20' wide backboards are very popular, especially in the 10' high series. Bakko feels a 12' backboard is adequate if only 1 person hits. If occasionally or potentially 2 people may practice, a 16' backboard is recommended. If 2 people hit and elegance is important, a 20' backboard is a must. Schools and tennis camps sometimes purchase 6, 7 and 8 panel kits, several panels for a continuous wall.
