Built for Winter Pool Closing
Solid Cover Fabric
Solid polyethylene construction helps create a barrier against leaves, debris and sunlight while the pool is closed for winter.
5-Foot Overlap
The 23' x 45' cover provides extra material beyond the edge of an 18' x 40' pool so the cover can float properly on the water and be secured around the perimeter.
Water-Tube Ready
Integrated sleeves and perimeter attachment points allow the cover to be secured using compatible water tubes or winter cover weights.
UV-Resistant Construction
The cover material is treated for resistance to ultraviolet exposure, helping it withstand seasonal outdoor use.

Frequently Asked Questions
What size pool does CO142345R fit?
The CO142345R is designed for a standard 18' x 40' rectangular inground swimming pool. The cover itself measures approximately 23' x 45'.
Why is the cover larger than 18' x 40'?
The additional material creates a 5-foot total overlap, or approximately 2.5 feet beyond each side of a standard pool. Winter covers are designed to float loosely on the pool water rather than being stretched tightly across the opening.
Does this cover have grommets and water-tube loops?
Yes. The Silver King cover includes perimeter attachment grommets and integrated sleeves/loops designed for water tubes and compatible winter cover weights.
Are water tubes included?
No. Water tubes, wall bags, cover pumps and other winterizing accessories are sold separately unless specifically included in the product listing.
Does water pass through this cover?
This is a solid winter cover, not a mesh cover. Its solid construction is designed to minimize water, debris and sunlight passing through the cover fabric. Rain and melting snow can collect on top and should be removed as needed with a suitable cover pump.
Is this a safety cover?
No. This is a traditional weighted winter cover and should never be treated as a load-bearing or ASTM-certified safety cover.
