ABSTRACT:
In a telescoping seating system, handrail support posts are mounted at the sides of the telescoping rows. Upper and lower handrail members are releasably clamped to the posts by a clamp assembly which includes a locking bolt received in an associated post, and a clamp nut received on an associated locking bolt and including means preventing rotation of the nut relative to the post. A quarter-turn motion of the bolt cams the clamp nut to securely hold the rail against the post, while a reverse quarter-turn motion of the bolt loosens the clamp nut and permits removal of the rail members only.
