Abstract
A drain assembly for a lavatory basin which includes a drain tube having a flanged upper end adapted for support by the basin. A drain plug is carried within the drain tube. A lift rod extends through the drain tube at a side opening therein and engages the plug. The lift rod is held in a sealed relationship against the tube by a retainer clamp which permits the lift rod to be shifted causing the drain plug to be correspondingly shifted between open and closed positions.
