Side mounting
Once the hooks have been fixed in the slots, the crossbars are inserted to form the side. Usually you insert the first crossbar at the first pair of hooks at the bottom and the second at the last pair of hooks. Use a hammer to allow the crossbar to go perfectly to beat on the pair of reference hooks. If required for range reasons, they can be inserted from three to multiple crossbars into a single shoulder. To complete the assembly of the side, you can use the feet in sheet metal or plastic.
