The PoolTux Royal 21ft Round Above Ground Winter Cover – GPC-70-9104 is blue on top / black on bottom and comes with a 10 year warranty / 1 year full. This winter pool cover is constructed of a triple laminated polyethylene material with heat sealed seams for added strength. Edges incorporate a sewn-in polypropylene cord for reinforcement. Aluminum grommets spaced every three feet. Deluxe aluminum cable winch and vinyl coated steel lock-down cable included.
Cover Clips grip your top rail like a clothespin and hold your cover on tightly. Cover clips keep your above ground pool’s cover in place and helps reduce the wear and tear on a winter cover from wind damage.
These rugged 16-gauge vinyl Air Pillows absorb freezing water’s pressure and helps protect your pool walls. The Air Pillow also reduces excess rain, snow, and leaves on your winter cover. Use an air pillow under your winter cover and it will also make draining the water off the top of your cover much easier.
