At the 2" OD size, the arm rail bracket carries the upper rail along the top edge of a bar counter at forearm height — a comfortable place for patrons to rest while they order or talk. It holds the heavier tube solidly to the bar structure, giving the top rail a bolder line. The arm rail is the upper of a bar's two rails; a separate footrail bracket runs the lower rail down where feet rest, and most full bars use both together. Polished brass suits a home bar, a backyard or basement pub, or a restaurant counter with traditional styling, and the bracket pairs with the matching 2" footrail brackets so one bar goes together from a single family of parts.
