Our safety pool covers are built using highest quality materials. We offer best quality polypropylene mesh, super strong commercial grade mesh and super dense ultra strong sun blocker mesh to craft our mesh safety covers. Super dense mesh blocks virtually all of the sunlight but still lets rain and melting snow easily drain through leaving debris out. It is the best choice for pool owners who want to see least debris in pool when they open their pool back in spring. Our mesh safety covers is strong enough to support at least 10 adults on top of it.
