To organize an increased degree of dust-tightness and moisture resistance for cable lines, a cover for the vertical downward T-junction of the "PLUS" series has been developed. The product is made of galvanized steel using the Sendzimir method. Intended for use in locations preferably with a dry climate, indoors, and in mildly aggressive environments, in accordance with GOST 15150-69. The element is used with a shaped section of the same series with a width of 300 mm that performs a downward cable route bend. The cover is fixed by snapping, and if necessary, it can be removed to gain access to the cable. The product is part of a system for constructing cable routes of any complexity at industrial, civil, and commercial facilities.
