Storm Sentinel catch basin inserts are the ideal products for preventing harmful pollutants from washing into storm drains. This frameless model is simple in design, powerful in protection, and the most affordable catch basin insert on the market. There are no special tools required for installation. The weight of the grate holds the unit in place, allowing extra fabric to be cut away for a custom fit. The geotextile fabric prevents contaminated sediment from washing into the drain while an Oil-Absorbing Packet can be added (-IB) to absorb oils. Use ENPAC Frameless Storm Sentinels to protect the environment and prevent fines and fees.
