Barclay 5577-PN is a water supply tube kit that includes the parts needed to connect a faucet to the water supply in your floor. The kit includes four cone washers, two plated locknuts, two supply tubes, two escutcheons, and two brass locknuts.

To assemble the tubes, first shut off the water supply and remove the old water supply tubing. Then, put a cone washer with the wide end of the washer inward onto the upper end of each supply tube. Slide a plated locknut up to the top of each supply tube and slide one of the escutcheons up the tube partway. Then, slide the brass locknut onto the end of each tube directly under the escutcheon. Finally, put another cone washer with the wide end of the washer downward onto the bottom end of the tube.
