If you use a cover lifter and a floating blanket this is something you wont know how you ever did without. The Floating Blanket Leash attaches your floating blanket to your spa cover so that when you open your cover, and remove it with the cover lifter, the floating blanket is automatically removed at the same time. No longer will you need to manually remove your floating blanket, and figure out where to put it when you use your spa. Your floating blanket will also remain clean since it will be gently hanging over your insulating cover on top of the cover lifter.
