Before installing KoolGrips, wet the covers in the pool water and wet the rails, this will allow the material to expand, allowing you to smooth the wrinkles out of the cover as you zip them up for a nice smooth finish. A extra large #10 Zipper has been used on our product to help with the zipping up of the cover. Its a TIGHT fit and has to be to produce a semi-non slip surface.
