Pre-Punched Slotted Holes

Pre-punched slotted holes in a side frame provide two advantages. The truck body may be prepped for door mounting prior to the arrival of the roll-up doors dramatically reducing installation times while delivering increased production consistency. In the field damaged side frames may be replaced in a matter of minutes knowing that the replacements will include slots that correspond to original mounting locations on the body. Slots are located within the center channel of the side frames at standardized intervals.
