11/16" & 2-7/8"
Lower section: between 1-7/8" & 2"
What is the inspection criteria for the upper coupler plate? - ANSWER Examine for gouges from fifth wheel, lubricated with grease, excessive/uneven wear, dishing, bulging, or distortion upwards. Check for corrosion and/or blockage of drain holes.
What is the inspection criteria for the main rails? - ANSWER Sight along main rails to notice deformation (twist, bow, dent, or bend) in framework; examine frame welds for cracks
What is the deciding factor in repairing main rails? - ANSWER Rails must be repaired when deformation influences the ability of a container to be seated properly and secured to the chassis, or its ability to track properly.
