Section 6.4: Final tightening
21. Finish tightening the four screws on the outside corners of the plastic coupler. Tighten even-
ly, in an automobile X type pattern as shown in Figure 6.41. If you do not tighten evenly,
you may break the fastener. Once the outsides are firmly tight, tighten the two screws that
hold the fiberglass spreader in place. Figure 6.42 shows the suggested method for tighten-
ing the screws.
22. When completely tightened, the sweep coupler halves should have gap of about 5/16” – 3/8”,
as shown in Figure 6.43. This gap is not critical as the coupler is mostly to keep the spread-
er in place properly. It is best to let the screws sit for a while (15-30min) and tighten in inter-
vals in order to allow the plastic clamp material to re-form. This also will reduce the chance
of snapping a screw.
23. Figure 6.44 shows the completed sweep—repeat the process for each sweep.
