The most radical freeform shape is probably the L-shaped pool, and depending on the shape of your yard, it may be the perfect configuration of your backyard pool. Although there are various ways in which an automatic cover can be installed on an L-shaped pool, including a single-mechanism installation where the cover is permitted to slide across portions of the deck, an ideal manner in which to cover this type of pool is a dual-cover installation that includes two separate mechanisms. With the turn of a key or the activation of a touchpad control, the two covers simply meet in the middle, providing the same level of security afforded by a single-mechanism installation without the visual distraction of tracks anchored to the top of the pool deck.
