Ultralift Undermount is the same easy-to- use cover lifter, but with an Undermount bracket that slides under your tub prior to filling. No need to drill holes in the deck, patio or spa skirt. One person can easily lift the hot tub cover off and position it behind your spa from outside or inside the tub.

Remember to allow for approximately three times the depth of your cover behind the tub, as the Ultralift Undermount slides down behind your tub when open.
