<p>The invention relates to a multi-member channel bar used as a passageway for power and telecommunications cables, as well as for use in construction. The multi-member channel bar, comprising openings along its entire length and provided with a connector (1) in the shape of a rectangular prism having through-holes (19) extending in crossing directions, is characterized in that it comprises superimposable members, each having an upper superimposable connecting section (2) and a widened lower superimposable connecting section (3), and slide-in members, each having an inner slide-in connecting section (14) and a widened slide-in connecting section (13). Each superimposable member, at its widened lower superimposable connecting section (3), has a tongue (7) provided with a latch (8) and cut-outs (12) formed above the tongue (7) and leading projections (5) formed below the tongue (7), while each superimposable member, at its upper superimposable connecting section (2), has leading projections (4) under which there is an opening (11) for the latch (8) and below the opening (11) there are holes (6). Each slide-in member at its widened slide-in connecting section (13), has projections (15) and cut-outs (17), and, at its inner slide-in connecting section (14), it has projections (16) and cut-outs (18).</p> |
