One pair of polypropylene straps, ergonomically designed to encourage proper lifting techniques. Designed to reduce back injuries due to heavy and repetitive lifting. These straps employ leverage which makes the items being carried seem 66% lighter, making it much easier to go up and down a flight of stairs, and turn around corners. Each strap is 9’ 4” (284.5 cm) long. They are adjustable up to 48” (122 cm) so you can easily carry small, medium, large and extra-large items.
