Designed for Winter Protection
Solid Polyethylene Barrier
Solid woven polyethylene helps reduce leaves, debris and sunlight from entering the pool while it is closed for the off-season.
Hold-Tite Reinforced Seams
Reinforced seam construction is designed to resist ripping, fraying and separation during normal seasonal use.
5-Foot Overlap
The 23' x 45' finished size provides extra material around a standard 18' x 40' pool so the cover can be positioned properly without being stretched tightly across the opening.
Water-Bag Ready
Perimeter grommets and vinyl attachment loops allow compatible water bags or tubes to be positioned around the pool deck to secure the cover.

Frequently Asked Questions
What size pool does GLI 45-1840RE-EST-5-BX fit?
This Estate cover is designed for a standard 18' x 40' rectangular inground swimming pool. The actual cover measures approximately 23' x 45'.
Why does an 18' x 40' pool use a 23' x 45' cover?
Traditional winter covers require extra material around the pool. The 23' x 45' finished dimensions provide a 5-foot total overlap, or approximately 2.5 feet beyond each side of a standard 18' x 40' pool.
Is the GLI Estate cover solid or mesh?
It is a solid polyethylene winter cover, not a mesh cover. The solid fabric is designed to create a barrier against leaves, debris and sunlight during the winter closing season.
Does this cover have grommets and water-bag loops?
Yes. The cover includes perimeter grommets along with vinyl loops/straps designed for use with compatible water bags or water tubes around the pool deck.
Are water bags included with the cover?
No. Water bags, water tubes and other winter-cover accessories are sold separately unless specifically included with your order.
Should this cover be stretched tightly across the pool?
No. A traditional solid winter cover should have adequate material to rest on the pool water and extend onto the surrounding deck. Avoid pulling the cover tight across the pool opening.
Will rain and melting snow collect on top?
Yes. Because this is a solid winter cover, rain and melting snow can accumulate on the surface. Standing water should be removed as needed using a suitable winter cover pump.
Is this a safety cover?
No. The GLI Estate is a traditional weighted winter cover and is not designed or certified to support people or animals.
