Keep Zeng chairs from drifting apart with Regency's 4400 Ganging Brackets. The Brackets come two to a set and latch any two Zeng series chairs together. The base of any Zeng chair fits snugly into each side of the bracket, keeping the chairs in neat, orderly rows. Removal is easy with a thumb grasp on one side. The Bracket is constructed of a sturdy hard black plastic that blends in with the black Zeng chair bases.
