 on top of the 3/8" screw as shown in Figure 9.

 located on the CabRac base one inch from the end, as shown, tighten
 using a5/16" Allen Wrench. Reference Figure10. Torque to 270 in/lbs.
4. Repeat for opposite side.
5. Go through all bolted connections and ensure that they all are fully 
 secured and tightened to the recommended torque.
Notes:
For good performance and safety, we recommend re-torquing all clamps and fasteners to the proper specifications after 
the first 500 miles and every 5000 miles thereafter.
Carrying high loads over rough roads with excess speed may damage the system on your truck. Exercise good judgment 
at all times.
