TM 10-1670-268-20&P 0004 00 0004 00-15 (2) Because of the tongue-and-groove interlock (1) the platform must be assembled from front to rear. (3) Examine the tongue-and groove (1) of the panel to determine which edge of the panel is the leading edge. Its protruding tongue and three holes close to the leading edge distinguish the leading edge. (4) Place the next panel on the supporting structure with tie down rings facing downward and the leading edge of the second panel next to the trailing edge of the first panel, and interlock the mating tongue-and-groove of the first and second panels. Slightly raise the second panel above the first to enable the tongue to drop into place within the groove.
