Drain Cover does the Job!

We keep these covers in our stock in case of a chemical spill. We did have a smaller spill outsdie that required a cover over one of the drains. The drain cover held the water back from going down the drain as we washed up the area. Basically no chemical would have gone down the drain due to the socks and mats we use from New Pig, BUT the cover was an extra measure to protect our city water and creeks. It is the right thing to do!

Drain Cover

Delivery was quick. I would definitely purchase it again. I have not have a chance to use it. It was bought for emergency spills. the product was heavy and durable, adn I think it will do the job when needed.
