This is the most popular cover lifter for Arctic Spas. Extremely sturdy with safety lock to prevent the wind from blowing the cover down while you are in the hot tub. Gas shocks are built in to help assit the lift off of the cover. Able to handle years of use in extreme weather, much much better than cheaper lifters. The cover rests up high so the cover can block the view from overlooking neighbors or helpd block a prevailing wind. If you dont want to block the view the next best cover is the Cover Basket.
