McAlpine DC1-BL-BO black drain connector with a 4"/110mm O-seal socket and 1½" universal boss.

Before ordering: for above-ground, ground-floor use only. McAlpine restricts this boss connector to the ground floor because its internal outlet diameter is reduced. It is not for underground installation. Check the receiving pipe, boss connection and installation against McAlpine's instructions.
