    For the C type, is the width always same as the two-posts rack frame? which is 3 inch wide?

    There is no set dimension for the side channel of the racks. Each manufacturer has their own design for the side channels or side posts. Some manufacturer’s have different types of uprights available for their racks depending upon what types of equipment your are installing.
