The Monkey Bars Play System combines four unique overhead ladders into one exciting structure. Kids can start on the middle deck or at one of the four vertical ladders. Next, they hold on tight and swing to the other side. A simple but fun premise. The four ladders consist of the Overhead Straight Snake Loop Ladder, the Overhead Straight Rung Horizontal Ladder, the Overhead Straight Trapezoid Loop Ladder and the Overhead Single Parallel Bar Ladder. All bring something different to the table. The Overhead Straight Snake Loop Ladder’s metal bars create a serpentine pattern; making swinging a little more challenging. The Overhead Single Parallel Bar Ladder requires proper gripping. The Overhead Straight Trapezoid Loop Ladder is easier to grab and lets kids hang a little closer to the ground. Lastly, the Overhead Straight Rung Horizontal Ladder is the familiar unit we all know well. Children can choose to play on one or all of them to have a blast.
