Manufactured by McFarlane Aviation, the MC0511240-5 incorporates design improvements developed from extensive evaluation of original seat rail wear patterns. The rail includes additional material in critical wear areas to improve crack resistance and strength while maintaining compatibility with original aircraft installations. The anodized finish provides enhanced resistance against corrosion and wear caused by seat movement, environmental exposure, and repeated maintenance cycles.

Unlike some original seat rails, McFarlane replacement rails are supplied without fully pre-drilled rivet hole patterns, allowing installers to precisely match the aircraft floor configuration during installation. This design approach accommodates variations between individual aircraft and helps ensure accurate fitment during repair or replacement procedures.
