ABSTRACT:
An arm locking system for a vertical banner supporting column having horizontally disposed arms. The tubular column internally receives a nut having resilient fingers permitting unilateral installation of the nut adjacent an arm extending through holes formed in the column. A screw within the nut bears upon the arm forcing the arm against the edges of the associated column holes frictionally positioning the arm and column. A single nut and screw may be used to position a plurality of arms upon the arms being so related that the screw causes engagement of the arms portion's within the column to engage in a frictional relationship forcing the arms into contact with their associated hole edges.
