Abstract
A pop-up drain assembly for a sink has a drain stopper, a generally vertical control rod and a generally horizontal pivot rod. A connector device links the control rod to the pivot rod. The connector device has compressive-friction connectors that receive and hold the control rod and the pivot rod. The connector device preferably has a pair of opposing C-channels that define a hole therebetween, where the control rod is received through the hole and within an open C-shaped space in the C-channels, and preferably a two-prong fork, where the pivot rod is held in a compressive-friction fit between the prongs on the connector device. The drain stopper preferably has a dual-prong fork, and the pivot rod is received between the prongs on the drain stopper in a compressive-friction fit.
