Product details

This is a closing bundle for a 21 foot round above ground pool. The cover measures 25 feet, which leaves a 4 foot overlap all the way around, and it comes with the hardware and chemicals needed to shut the pool down for the season.

The cover

It is a solid cover, 5 mil, made from triple laminated polyethylene in blue on black with heat sealed seams. A polypropylene cord is sewn into the edge to spread the load, and aluminum grommets are set every three feet for the cable. A deluxe aluminum cable winch and a vinyl coated steel lock down cable are supplied to draw it tight. The cover carries a 10 year warranty.

What else is in the box

A 15k chemical closing kit treats the water as the pool goes down, and a 4 foot by 8 foot air pillow goes under the cover before it is secured. The pillow does two jobs over winter: it absorbs the pressure of expanding ice so the pool wall does not have to, and it crowns the cover so rain and melt water run to the edges instead of collecting in the middle.

Questions and answers

What people ask about this product, answered by our pool techs.

What size pool is this for?
A 21 foot round above ground pool. The cover itself is 25 feet, which gives the 4 foot overlap you need to secure it.
What comes in the box?
The round winter cover, a deluxe aluminum cable winch, a vinyl coated steel lock down cable, a warranty card, a 15k chemical closing kit and a 4 foot by 8 foot air pillow.
What is the air pillow for?
It floats under the cover in the middle of the pool. As the water freezes and expands, the pillow takes the pressure instead of the pool wall, and it also keeps rain and melt water running to the edges rather than pooling in the center.
How is the cover held down?
The cable threads through the aluminum grommets, which are set every three feet, and the winch pulls it tight around the pool. The edge has a polypropylene cord sewn in to spread that load.
