K-4991-ET Bardon™ High-Efficiency Urinal (HEU), washout, wall-hung, 0.125 gpf to 1.0 gpf, top spud

The newly redesigned Bardon urinal provides flexible flushing options along with a bold new contemporary look. Based on your selected flushometer, the Bardon operates in the range from 0.125 (1/8th) gallon to 1.0 gallon per flush. When paired with a 0.125 gpf flushometer this urinal is ideal for water conservation installations, and qualifies as a High-Efficiency Urinal (HEU) that can help a building earn Water Efficiency points in the LEED® Green Building Rating System.
