Assemble the Rail (Continued)

4.Beginning with the sprocket end, 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 another brace on the opposite side of the rail over the bolts, add 1/4"-20 lock nuts, and hand tighten. Insert two additional bolts and hand tighten.

7.Keeping the rail straight and on a level surface, grasp the screw rods on each side of the remaining joint and pivot into a straight line. Repeat steps 5 and 6.

8.With a 7/16" wrench, tighten bolts until snug, beginning with the center holes. Do not overtighten.
