Description
Lawson Aquatics white 18 Inch (in) x 18 Inch (in) FLAT GRATE ONLY, no frame or hardware.
Used as grates for sumps with larger frames that require multiple grates, such as MLD-FG-1836-WT (18″x36″). Install drain covers that meet ANSI/ASME A112.19.8-2007 standard on EVERY drain/grate. Install an automatic shut-off system, gravity drainage system, Safety Vacuum Release system (SRVS), suction-limiting vent system or disable the drain, if the pool operates off of a SINGLE main drain. Pools and spas with unblockable drains are exempt from this requirement. Ensure that dual or multiple main drains are at least 3 feet apart.
