Filter Sock

Filter Sock is used for Building and Construction Site drainage and Agricultural drainage. Filter Sock is designed for use with perforated plastic drainage pipes and is designed to slip over the pipe to prevent particles and fines entering the pipe and clogging the flow. The Preloaded Filter Sock comes loaded on a cardboard inner core which slides over Novaflo pipe. When in position, the cardboard inner is pulled back out from beneath preloaded sock leaving it wrapped around pipe. This saves time trying to stretch the sock onto the pipe.
