The Ultralift Undermount conversion kit allows for you to change your standard cover lift into one with an undermount. With this undermount, there is no more drilling into the side of your spa to install a cover lifter. This is bought in addition to a Ultralift cover lifter.
The CoverMate II Understyle Cover Lifter is there for you when you need it and tucked away in the background while your hot tub is in use! It has two plates that slide easily underneath your hot tub. The cover lifter only requires 18 inches of clearance behind your spa.
