Magnetic Spill-Control Drain Covers
Stop oil, chemicals, and other spills from going down the drain with these magnetic covers. Powerful magnets hold them in place on metal grates and drains for a tight seal that stays put. The durable vinyl construction won’t tear or degrade from exposure to spills or repeated washing.
