The pipe-mounted coupler enables industry standard hooks on horizontal rods and other accessories to rest at such a height as to provide uniform appearance to the top of drape walls. The pipe-mounted coupler mounts on a pipe or rod vertical end to allow one or more accessory connections to be affixed to the vertical pipe. The pipe-mounted coupler includes a locking protrusion that is insertable into a slotted opening on the pipe end to allow the pipe-mounted coupler to be secured onto the pipe end allowing minimal vertical movement or horizontal twisting.
