Laminated polyethylene sheeting woven with thick, high-density polyethylene stitching ensures superior tensile strength and durability. All covers are treated to provide maximum resistance to damaging ultraviolet rays to inhibit deterioration and increase longevity. In-ground pool covers come with standard holding straps for water tubes, optional reinforced webbed border for additional strength and durability and feature conveniently positioned, corrosive-resistant grommets for easy securing.

The Swimline 10 Foot Double Water Tube is 33% heavier then other water bags (14 Tubes Total). The valves are easy to fill up with a garden hose. This is used with an in-ground pool cover.

Prepare your pool this winter with our pre-measured winterizing closing kit. Our powerful combination of winterizing chemicals help to prevent algae growth, eliminate minerals and metals that can cause liner stains and build-up, and purge lotions, oils, grease, and grime from your pool water. Ordering a larger winterizing kit than your pool size may help to protect against winter cover problems.
