This flat surface mount is used as an alternative mounting option to go from Rehadapt to Locline components. This mount will also work with other products that have a flat mounting surface; allowing for switch mounting, phone mounting, etc. to Rehadapt mounts or systems that utilize a 20-22mm pipe. All instructions for printing and assembly can be found in the "Rehadapt_to_Locline_20mm.pdf" file.
