McAlpine BossConn 82mm 3" Plastic Pipe – 1.25" Universal Black
Product Description
The McAlpine Boss Connector is a plastic adapter piece designed to join an 82 mm pipe entry (often wall or floor boss) to a 3″ waste pipe, while blanking off the 1¼″ (32 mm) uni opening. This allows a clean and secure transition with one inactive outlet.
