The table top rests on the side parts. They are orthogonally welded together from the table legs and the cross struts, which connect the legs in pairs, and result in a "H with two cross lines" so to speak. The side panels of the E2 table frame are available in six sizes. When selecting the side sections, it is important to determine here whether the E2 table frame has a central or a staggered cross strut. The holes for connecting the side parts and cross struts are not provided in each side part for both variants. Therefore, if you later wish to move the cross struts, for example, you would have to get other side parts. Or put differently: Once you have made up your mind, your E2 table frame will remain one with a cross either in the middle or offset. We recommend for example for a work table placed on the wall offset and for a table freely placed in the room used from both sides central cross struts.
