This is a pool safety cover extension strap measuring 4 feet.
Extension straps may be used when the standard strap is not long enough to extend across a surface to reach the desired anchor location. Extension straps are available in 4, 6 and 8 feet. Straps in excess of 8 feet are not recommended, as they could lead to wind whipping and premature wear. Avoid more than 20% of extension straps on a cover.
