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.
