Ladder Placement
Starting Location of Ladders
Ladder placement is very critical as to assure proper fit of all parts later on as safety cage is bolted in place.
Locating proper placement of the roof ladder and manway will establish the location of the ladder. Ladder
must be centered directly below the roof ladder. Refer to
Figure 6F below for proper location of field drilled
holes (3/8"). Holes must be 18-3/4" apart and 2.66" below the top horizontal row of holes directly in line
with the pre-punched holes in the horizontal seam. Platform mounting angle must be located 9-3/8" to the
right of the ladder holes. All of these dimensions are very critical to assure proper fit of all parts.
