Petroleum sorbents repel water while absorbing oil and petroleum-based loquids from oil spills and effluent discharges. Sorbent material is secured by a UV resistant netting. Built-in attachment clips are provided at each end of the boom allowing the booms to be linked together, overlapping and preventing seepage between segments. Choose single boom in 8" x 10' long available 4 per case or "double" boom in 4" x 10' long also available 4 per case. Absorbs upto 80 gallons each.
