The MOT Cleat Rail is a lowprofile aluminum Tslot / Tchannel rail that runs along the top of the front and rear MOT ExoFrame crossbars to expand gear tie-down options. It is dimensionally matched to the Toyota Tacoma factory bed rail system (Gen 3/Gen 4) and Jeep Gladiator bed rails, enabling the use of a wide ecosystem of Tslot accessories. When paired with appropriate Tnuts and hardware, the rail can accept many mounts from leading brands (Yakima, Thule, RhinoRack, etc.). The MOT Cleat Rail attaches to the ExoFrame with four M8X16 hex screws. Lost one? No worries, order a replacement.
