A cable channel made in the form of a box comprises a base with two sidewalls, either has a longitudinal groove on the outside surface, and provided with a cover having two sidewalls, either has longitudinal projection turned inside the box and made with ability to be installed in the longitudinal groove. Besides, every longitudinal projection located on sidewalls is realized in cross-section in the form of a right-angled triangle with a right angle directed to cover base, and a leg being extension of a cover wall. Every longitudinal groove located on sidewalls is made under acute angle to the box base as hook-like cross-section that has a flat aria from side of the cover base that may be located on cover projection. |
