4. Straighten the two rail sections so that the screw rod is
in a straight line at the joint. (Avoid handling the joint,
which may have sharp edges.)
5. Carefully slide the pins at the top edge of the rail into
the openings on the adjacent rail. It is essential that
the rail assembly be on a level surface to achieve
proper alignment and to avoid damage to the pins.
6. Insert two 1/4"-20x1-3/4" bolts through the center
holes of a brace, and place its open length against the
rail at the joint, aligning the holes as shown. Position
the other brace on the opposite side of the rail over the
bolts, add 1/4"-20 lock nuts, and hand tighten. Insert
remaining bolts and hand tighten.
7. With a 7/16 wrench, tighten bolts until snug,
beginning with the center holes. Do not overtighten.
