Beautiful Unlacquered Polished Brass finish, solid brass construction, keeps dust out of stair corners, authentic reproduction. Born out of a need to simplify housework back in the 1890's, these solid brass dust corners add an element of charm and distinction to staircases today. From point to point these stair corners measure 2 3/4''. Each stair corner includes matching nail. These stair corners are hand finished so there may be slight differences in the finishes.
