An endwise pushdown guide and lateral restraint fitting for cargo having a base adapted to be secured to an aircraft subfloor. The base supports to a pair of parallel pivot pins and pivotally secured on each pin is a respective blade normally extending in an upright position. Each blade is supported by a pair of lugs through which a respective pivot pin extends, the pin for each blade being remote therefrom to provide a moment arm from the pivot to the blade. The blades are parallel and have respective ramp surfaces, tapering toward the direction from which cargo may be moved along an aircraft floor. Thus, when a cargo container is moved against one tapering surface the horizontal force thereof has a downward component which acts on the tapering surface and the moment arm of that blade to cause the blade to pivot downwardly under the container so that it can be moved past what would otherwise be a restricting blade, the blades being adapted to restrict cargo on their lateral surfaces outwardly of the supporting base and pivots.
