Matala Hakko Air Pump Support Stands Size:Fits HK-40L / HK-60L / HK-80L Outside 63"W 47"D 85"H 4ftMatala Hakko Support Stands are designed to allow for installation of a Hakko air pump on a wall. Built with rugged plastic construction. Always mount your air pump above the water level of your pond or water feature. Do not rely on a one way check valve. The bottom of the air pump should be at least 2 inches above water level to prevent back flow into the pump. A flooded pump will not qualify for warranty.
