Robelle 18 ft Economy Winter Pool Cover for Above Ground Pools — Navy Solid Polyethylene with Winch

Robelle's 18 ft Economy Winter Pool Cover is a solid, navy-blue winter cover sized for 18-foot round above-ground pools, with a 3-foot overlap and included winch and cable for secure seasonal closing.

When you need a straightforward, durable way to close an above-ground pool for the off-season, this Robelle economy winter cover delivers a solid polyethylene barrier that blocks water and debris. Built from 7 x 7 scrim woven polyethylene at 2.2 oz/yd² and finished with a navy topside and black underside, the cover is designed to float loosely on winter water and resist snow and ice pressure. Robelle includes a winch and cable for perimeter securing and backs the product with an eight-year warranty.

How does this cover keep my pool protected all winter?

The Robelle solid winter cover prevents precipitation and debris from passing through the fabric, reducing contamination and easing spring clean-up. Its heavier-than-standard weave and solid construction create a dependable moisture barrier and a surface that sheds leaves and snow.

• Solid polyethylene blocks water transmission and most fine debris.
• 7 x 7 scrim woven construction increases material stability and tear resistance.
• Navy top and black underside help hide dirt and extend usable appearance.
• Designed to float to accommodate ice movement without tearing.

What size should I order and how does the overlap work?

Order the cover by your pool’s nominal size — for an 18 ft pool this cover includes a 3 ft overlap, making the overall material 21 ft across. The overlap provides extra material to drape over rails or decking, simplifying installation and allowing the cover to float without excessive tension.

• 18 ft cover + 3 ft overlap = 21 ft overall diameter of material.
• If your pool has a large top rail or bulky decking, consider the next size up for a relaxed fit.
• Overlap helps secure the cover with clips, wrap, or water bags where needed.
• Cover is intended for traditional above-ground pools with a standard top rail.

How do I install and secure the cover correctly?

Robelle supplies a winch and cable to thread through the grommets around the perimeter and tension the cover from the outside. This method is recommended for best performance in windy conditions; additional accessories like cover clips, cover wrap, or vinyl water weights can be used for extra security on decks or partial-deck installations.

• Use included winch and cable to cinch cover taut through grommets.
• For decked pools, place vinyl water weights on top of the cover where needed.
• For partial decks, run cable under deck where possible and use water weights on decked areas.
• Do not rely on other non-recommended fastening methods for long-term security.

What should I know about material, durability, and warranty?

This cover is made from polyethylene at 2.2 ounces per square yard with a 7 x 7 scrim count, a combination that provides sturdiness for seasonal use. Robelle builds the cover roughly 10% heavier than common industry standards and supports it with an eight-year warranty to cover manufacturing defects.

• 2.2 oz/yd² polyethylene with 7 x 7 scrim for improved strength.
• Constructed approximately 10% heavier than typical economy covers.
• Solid design resists snow and ice pressure when allowed to float.
• Includes an eight-year warranty from Robelle against defects.

Who is this cover best for? The Robelle 18 ft Economy Winter Pool Cover suits pool owners who want a reliable, no-frills winter closing solution for a standard 18-foot round above-ground pool. It’s ideal if you prefer a solid cover that limits water and debris ingress, appreciate the convenience of included installation hardware, and want a product backed by decades of experience and an eight-year warranty. If your pool has oversized rails, custom decking, or you need a debris-season cover for swimming months, consider sizing up or choosing a different cover type.
