4420 & 4422Taper Thread Plug with Round Access Cover

These Duco coated cast iron ferrule cleanouts are installed in hub openings on drainage piping where a cleanout is required. The cast bronze taper thread lead seal plug can be quickly and easily removed for cleaning. The ferrule is ribbed on the outside to prevent turning of the ferrule in the caulking lead. A shallow stainless steel cover and deep chrome plated cover is available if desired for finished walls.
