Drain covers, guards and plugs are versatile products that protect drains. Drain covers are lightweight, low-profile units that block contaminants. Cost-effective neoprene drain covers can withstand air and oil exposure. Flexible PVC (polyvinyl chloride) is extremely durable and chemical resistant. Drain guards prevent contaminants from entering water systems. The narrow, conically shaped portion of the drain guard blocks unwanted particles while allowing water to pass. Drain plugs block entryways and other open areas of drainage systems to prevent spills and leakage. Most drain plugs are conically shaped to fit securely into the drain. A metal eye at the top of the drain plug allows simple insertion and quick removal.
