The final piece of the puzzle to create a "perfect" installation of a Duraflex Diving Board onto a Durafirm Diving Stand is to make sure the Roller Clamps ("C" shaped metal bands that hold the fulcrum roller to the fulcrum assembly) move between the 1st and 2nd "rib" of the diving board (on the foot wheel side) and between the 7th and 8th "rib" of the diving board on the non foot wheel side of the board.
If you get the 2nd element of a "perfect" installation correct AND you get one of your Roller Clamps to line up as shown in the photo above (between ribs 1 and 2) -- then the roller clamp on the other side of the fulcrum assembly will line up exactly the same on the other side of the board (between ribs 7 and 8). Since the rubber channels of the board and the slide tracks of the fulcrum are parallel (see part 2 of 3) -- the roller clamps will stay positioned between the ribs as the fulcrum is rolled back and forth.
The situation you want to avoid is where the rib of the diving board is directly on top of the roller clamp. When the diving board is bounced, it puts undue stress on all the working components of the fulcrum assembly and usually means your board is out of alignment and therefore not bending "squarely" over the fulcrum.
