You May Never Use Pegboards Again There are no pegs to slip out or lose, reducing the potential for accidents. Power Climbers will easily handle up to 200 lbs. of weight. Recommended for use through 8th grade level. The Power Climber is 41-1/2" tall x 12" wide (105.4cm x 30.5cm), with 7 rungs per side. Angles out away from the wall so climbers do not slide over the lower rungs as they climb higher. Made from hardwood, and is shipped complete with mounting hardware.
