This Over Rail version of our Classic Birdbath has a simple copper bowl with a wide rim for birds to perch while drinking and bathing. The threaded base on the underside of the bowl attaches it to the center of the Over Rail Bracket. Ideal for porches, balconies or deck rails, the wrought iron bracket has C-type clamp that holds the bracket to a deck or handrail without need for drilling or permanent mounting. Fits railings up to 5 1/2" wide and designed with ample clearance for a curved top handrail.
