1.0 inch of vertical adjustment (up or down) after runway installation.
Provide rods with self-aligning gimbal or ball-and-socket joints at each
end which allow at least 5.0 degrees of deflection from the vertical.
Provide not more than two rods per suspension point and in such cases
consider the unequal loads induced in the rods. Fluid-filled load
equalizing cells are not acceptable.
