McFarlane states that its Cessna seat rails are anodised for corrosion and wear resistance and incorporate additional material in critical areas for improved crack resistance and durability. The rail base is supplied without factory pre-drilled rivet holes, enabling the attachment-hole pattern to be matched to the aircraft floor during installation; special-sized or machined attachment holes are finished at the factory. Existing stock may have limited pilot attachment holes.

The manufacturer lists MC1210520-9 for Cessna 210K and 210L, and T210K and T210L, within specified serial-number ranges. Verify the aircraft serial number, applicable approved maintenance data, part-number effectivity, and installation requirements before purchase or fitment. FAA-PMA status does not by itself establish EASA approval or acceptance.

Documentation: See the McFarlane MC1210520-9 product page and the McFarlane seat rails and extrusions catalogue for manufacturer eligibility and installation-reference information.
