A small column or pilaster, used as a support to the rail of an open parapet, to guard the side of a staircase, or the front of a gallery. See Balustrade.
One of a series of small pillars that is attached to and runs between the stairs and the handrails. The spacing between the balusters should be less than 4 inches to prevent small children from getting stuck between the balusters. Balusters are considered a safety item and provide an additional barrier.
One in a series of short posts or pillars supporting a rail.
