The PIG DRAINBLOCKER Drain Cover featuring DuPont Elvaloy Technology is designed to seal out liquid while providing life-long flexibility, chemical resistance and protection against UV rays. It features a high-visibility yellow top layer to draw attention to spills while the black bottom layer hides dirt and grime. It stands up to sunlight and harsh weather conditions and is ideal for quick spill response or long-term, outdoor deployment. Patent-pending vinyl composite top layer strengthens the drain cover to prevent stretching, ripping, and tearing under normal foot traffic. For more information visit www.newpig.com.
