Branch T-piece with flanged, round, and unperforated side rails, featuring connector holes for connections, with an integrated joint connector, designed for wide-span cable trays. It is shape-stable due to a rear-mounted support profile and the riveted, flanged, and unperforated base, allowing for cost-effective production of 90° T-branches and intersections, dependent on width in the main direction, including proportionate fastening accessories made of stainless steel. The radii of the fittings are designed to allow cable installation according to DIN/VDE 0298 Part 3. Joint points must be supported by an appropriate load-bearing structure in close proximity. Usable for wide-span cable trays WRL 105 and WRU 105. Dimensions (approx. measurements) clear height H x clear width B: 106.5 x 305 mm. Notch of the wide-span cable tray: 1003 mm + B.
