    Filter Sock

    "It works Great to keep run off and fluids from entering storm drains. The weight holds it in place during severe weather and rain and it does not move. I highly recommend it for storm drain management."

    Perfect sock for keeping debris from the drains

    "The sock was perfect for keeping debris from going into our drains during a recent construction project. It was also a great option for keeping oils from getting into the storm drain and the maintenance department appreciated the handles for carrying the sock. I love it is made with recycled materials and quality of the product is wonderful! I expect to have continued business from our company for many years to come. Thank you!"

    Quick Shipping

    "I haven’t actually got around to using this yet because it’s the middle of winter and about to drop below zero, but they arrived in like two days. I am assuming they are going to live up to my quality standards. I will let you know when I write a review on the 5 footers."
