Step 4: Mount one arm at a time to each side using the included 10-32 Rack Screws. Place the arm assemblies at the upper corners and lower corners. The more screws that you use to mount the arms , the stronger the overall rack will be. Each arm allows for six screws per side. To maintain the published weight capacity, six screws are required. To adjust the racks depth: Take out the 7/16 hardware in the arm assemblies and slide the two sides together or apart and reinstall hardware in the arm assemblies.
