The Spark Series Zipper Climber is a unique metal climber that can be added onto any custom play structure. It resembles a normal straight metal ladder, but instead of having horizontal steps that extend across the ladder, it has alternating rectangular steps on each side. These steps offer a stable, winding path that children can climb up to reach the upper platform of your play system. Children with larger arms and legs can climb using only the insides of the rectangles as steps, but if a smaller child has difficulty reaching that far with each step, they can use the top sides of the rectangles as well. The unique design actually makes it so that this climber is two separate pieces which makes shipping easier and more space-efficient. The Spark Series Zipper Climber is a great accessory that gives play structures both a fun way to climb and a dash of modern flair.
