3/8 in. O.D. x 20 in. annealed brass water closet supply riser, adds the finishing touch to any installation. Its trimm-able end allows cutting to length for easier installation. The top flat head portion attaches to the toilet ballcock, using a 7/8" nut. (Not included - comes with most toilets). Made from lead free brass and fully finished for exposed installation. Its sleek appearance gives shame to common flexible supply lines.
