This model is similar to the SF-59 but includes an added Spa-Side attachment for added support and rigidity. Includes the Lift & Turn Base, All Mounting Hardware and a side-attachment Slip-T for added support. Suitable for use with above-ground Spas up to 45" high. The "Lift & Turn" feature enables the user to rotate the rail 180 degrees with one hand for entry & egress and to facilitate covering and uncovering the Spa. Saftron Spa Rails are made of 1/4" thick hard-shell composites that are unaffected by spa chemicals (chlorine, acid & salt), and reinforced internally by Schedule 40 Galvanized Steel that adds strength and rigidity. As the reinforcing core is completely encapsulated, it does not come into contact with air or water, so it will never rust or corrode. The hard-shell nonconductive material meets applicable codes in all states without the need for bonding (grounding), thus making it ideal to install in any location without having to dig-up patio decks to install grounding cables.
