Extension Straps - Comes in a Set of 4.
Purpose: For a larger circumference of the handrails on treadmills:
Measure the distance around the handrails of your treadmill. The Walktop™ supports up to 12 inches (305mm) in circumference and a minimum of 4.75 inches (120mm) but may depend on the shape of the arms. If your treadmill arms are over this size, then you will likely need the extension straps. If the circumference is smaller than the minimum, you may need to place something around the arms first.
