Ultralift™ Visionlift™ LIFT-VB Boomerang Spa Cover Lifter is the second generation Visionlift™. We have eliminated the need to drill a secondary bracket location and streamlined the design. Using a dual shock system, it lifts the cover and places it behind the tub- providing the user with a clean visual line- allowing your client to see your backyard, socialize with guests and keep an eye on any children or pets while using their hot tub. The Visionlift™ provides a full 360 degree view.
