Coverlon Company In-Ground Swimming Pool Covers for Sale and with Free Nationwide Shipping from Family Leisure! In the world of swimming pool protection, nothing compares to a Coverlon cover. This family-owned company has been producing their covers since 1990 from Branchburg, New Jersey. While being American made is certainly a plus, it's the attention to quality, stability and durability that separates Coverlon from their competition. Coverlon offers several safety and winter cover products for in-ground swimming pools. Choose between solid green or blue vinyl-coated polyester or mesh polypropylene for your pool cover material. The solid cover will keep out water, leaves and other debris, while the mesh material is permeable, allowing water to trickle through while keeping the above mentioned undesirables out. Do you want to avoid the heavy water that can build on your pool cover? Coverlon's mesh material pool cover is for you, rather than the solid material which allows water to gather on the top. The mesh is available in either a Conventional Mesh Material or a Super Dense Mesh Material; both are extremely strong, with the Conventional Mesh offering a thread count of 34 x 22, higher than the industry standard of 34 x 20. Coverlon promotes all three types of materials as winter and safety covers, so your pool is safe and "covered" no matter the season. The sizes and shapes available are virtually infinite; we ask that you call 877-775-3478 for a price quote with Coverlon pool covers due to the custom nature of the product.
