g. A special nipple setting gauge is provided for
the nipples. Gauge nipple in both directions to
insure that it is driven to the proper depth into
the nipple opening (nipple port). Cut-out in
gauge must rest on nipple, with legs of gauge
touching finished face of section, when nipple is
properly driven. See Figure 6.
h. Remove a 96” length of fiberglass rope from the
assembly carton. Starting with the area around
the upper 7” nipple port, firmly press the rope
into the groove, so that the adhesive holds it in
place. (If more than 25 minutes have passed
since the adhesive was applied, it may be
necessary to reapply.) Continue to affix the
rope to the groove in this fashion around the
perimeter of the section. Make sure that the rope
does not droop or hang outside of the groove.
When the end of the groove is reached, cut off
the excess rope. Push the length of excess rope
into the groove at the top corner of the section
face (opposite of the 7” nipple port.) Cut off and
discard any remaining rope after groove is filled.
See Figure 7.
