The internal base and vertical bars for the Rhino-Rack Backbone Roof Rack Mounting System # RRRJKB1 are steel L-shaped bars. I went out to our warehouse with a digital caliper and measured the actual thickness of each bar to be right at 0.124 inch. They measure 1-1/8 inch x 1-1/8 inch.

I have attached a detailed installation video that you can check out as well.
