The new Ultimate II Swim Spa Cover is as strong as they come. 

UL Labs has proven that Advanced Spa Covers makes the strongest cover available anywhere. Here we show a swim spa cover that measures over 200" long yet it still supports the weight of a grown man with no issues and no concerns.
And even better than that, its possible for one person to open this cover with one hand. Check out our website at Advanced Spa Covers .com
