    Gets the job done!

    "I have purchased these drain covers multiple times. They do an excellent job keeping debris out of the drains with its heavy duty surrounding tacky seal. These work perfectly for indoor and outdoor use as they are very durable in all types of whether. Wouldn't buy anywhere else!"

    "We have purchased these in the past and they have performed exactly as advertised and we will continue to buy these going forward. We use these to prevent anything going into our storm water drains that we do not want in there. I would recommend these as a great drain blocker that will last a long time if you take care of it."

    Great Product

    "Useful in both indoor and outdoor areas, we have bought multiple times, durable and last a long time outside in all sorts of weather, price isn't the cheapest, but the cost is worth it"

    Great drain cover

    "Had some redundant drains covered from the California rain due to some debris that cause these to get plugged up and carried over to the nearby estuary. We used the PIG fiber covers on the other drains so to filter out all debris and sediments. Excellent products!"
