NOTE: When adding additional riser sections use a #10 x 1.5” stainless steel screw to fasten the sections together. ALL screws must be installed ineach riser section and cover to ensure a watertight connection. In addition, the structural integrity of the risers is also dependent on the fact that allscrews are installed properly. We recommend an alternate screw tightening pattern be used to ensure even pressure on the risers and cover.Failure to do this could cause the riser sections to compromise the seals and possibly fail.
