Waste Arm

Waste arms for sink and lavatory drains. The collection includes Dearborn 1-1/2" waste arms with slip joint or Hi-Line ends in 15" and 23" lengths for 16" and 24" end outlets, and Hi-Line/slip joint combinations with telescopic waste arms and 1/2" or 3/4" branches.

Measure from the trap to the wall drain to get the length, and choose a telescopic arm when the distance varies. Match the tube diameter, usually 1-1/2" for kitchen sinks, and check gauge, since 17 gauge is heavier than 20. A branch fitting accepts a dishwasher drain.
