Installation instructions for Polywater® FST-250 foam duct sealant. The FST-250 is a caulking-gun-style cartridge that delivers a robust, two-part, closed-cell foam that effectively seals water, gases, acids, insects, rodents, dust, and other debris out of electrical and communications conduits. FST™ foam is compatible with cables and ducts and provides vastly superior blocking strength than typical “open-cell” canned foams. Video demonstrates use of the cartridge and procedures for later removal of the seal, if required. Run time 6 minutes.
