Kit contains two (2) Aircraft Aluminum legs with rubber feet, 24.5" long, plus 4 fiddle screws for easy installation.
Simply insert legs at the bottom of the ramp. Place the curved section of the ramp on the side of the pool and place in pool with the legs at the shallow end. The ramp is designed not to sink in water, therefore the legs are hollow, allowing the legs to fill with water, which holds the ramp in place. The ramp legs have rubber feet to keep it in place as well as to protect the surface of the pool.
Can also be used with HalfSTEP II Multi-Purpose Ramp for side of bed or couch.
