    Nice Product

    "We used this product in a different manner to help funnel small debris into a barrel. To help catch the falling parts along side the opening of the barrel. Was a good fit and working well."

    Good Product

    "We use this in a different manner. We use this to filter water from debre and sediment from a shop vac. The water passes through this with ease except when heavy sediment accumulates, such as mud or muck."
