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