After the lifting fixture is removed, push the top of the seal against the
caisson and install all remaining nuts and washers.
Move the seal into position so that the mating surface at the mitered
joint is aligned with the previously installed seal assembly. There
should not be a gap or misalignment.
Once the seal is in position, tighten all mounting nuts one and a half
turns beyond the point where initial contact is made between the seal,
caisson, nut, and washer.
Application: Caisson wood seals should be replaced as required by new
"rubber" isoprene seals. Greenheart wood is NOT immune to marine borer
attack; DO NOT USE in saltwater or brackish water.
Future Inspections: Caisson seals should be visually inspected before each use
and if any leakage occurs.
