Very simply. When in place, a Kid Safe Pool Net is stretched tight enough across a pool to suspend a baby above the water. When it comes time to remove it, the Central Tensioning System enables you to release the tension from the net before unhooking the anchors, allowing a quick and easy removal. This is also true for putting it back on – hook the net in place while it is loose, then pull in the tension ropes from the edge of your pool to re-set the tension. On a standard 15 x 30 pool, the average user takes about 4 minutes to completely remove the net and about 8 minutes to replace it (including the re-tensioning). An experienced user takes about 2 minutes off and 5 minutes on.
