The rack bases establish the lateral stability of the rack system in the direction of the rack arms. Rack bases shall be manufactured of structural W-sections and shall be punched for anchor bolts. Typically the rack bases are the same length as the rack arms, but are not permitted to be less than the height of the column divided by seven, or minimum 1/7th of column height. 4. Braces a. Braces provide lateral stability to the rack system along the length of the system by tying each column together. Each rack system shall be braced with cross braces and horizontal braces. Braces shall be manufactured of structural angles and flat steel and shall be connected to the columns with ASTM A325 structural bolts. 5. Anchors a.
