Safety Cover Installation Tip: Follow the Grid
Whether covering a standard rectangle or a more complicated freeform pool, all safety covers are made in a perpendicular grid with straps running across the length and width of the pool.
When installing a freeform safety cover, remember the grid and be sure to keep the straps straight and parallel all the way across the pool from anchor to anchor. Misaligned straps can cause wrinkles, and in some cases tears, in the cover.
A good way to keep the grid perpendicular is to visualize the freeform cover as a rectangle, rather than focusing on the perimeter of the cover (see photo below).
