PoolTux King99 20 x 40 ft Mesh Safety Cover with Left Step, Blue, CSPTBMP20402

This King99 panel is cut for a 20 x 40 ft rectangular inground pool with the step at the left end. Step hand is read from the shallow end looking down the pool, so check yours that way before ordering. The fabric measures 22 x 42 ft, which is the pool plus a foot of overlap onto the deck on every side, and the step panel is 8 ft across and 4 ft back at the water line.

• Blue mesh at 7 oz with a published burst strength of 670 PSI.
• Rain and snowmelt drain through the weave into the pool instead of sitting on the panel.
• The weave stops 99 percent of ultraviolet light, which limits algae while the pool is closed.
• Straps sit on a 5 by 5 ft grid with commercial springs taking the tension.
• Brass anchors tamp flush into concrete or paver decking and retract with a hex key.
• Anti rub strips take the wear where the webbing passes over the coping.

The standard behind a cover like this is ASTM F1346. Its section 7 static load test applies 485 lb to a cover on a pool more than 8 ft wide, split into 210, 225 and 50 lb over a square foot each within a 3 ft radius, and section 7.3 asks for substantially all standing water to be gone 30 minutes after rain stops. A winter cover sits in the other covers group under section 4 and is not intended as a barrier. Section 8.12 puts the classification on the label so the difference is readable.
