The Woodford Model 68 Undercover Wall Hydrant is protected by an integral 16-gauge stainless steel cover. It is unique because it provides the protection of a box hydrant, but has a sleeker look (only protrudes 1" from wall) and smaller footprint (for easy installation) than a box hydrant. The tee key- operated stainless steel cover flips down for easy access. The hydrant won’t freeze and drains automatically, even with a hose attached, Woodford explains.
