If replacing one suction cover, it is highly recommended that you replace all of them to be compliant. These suction covers are available for replacement of your older suction covers (spa models pre-2009). There is however no guarantee that these suction covers will fit your pre-2009 spa.
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.
