The NetRunner™ Waterfall Trough creates an over-rack pathway to effectively route cables into the vertical manager channel with proper bend radius. The waterfall trough is expandable so it is compatible with Panduit 2-post and 4-post racks. The waterfall trough depth is sized specific to the NetRunner™ (WMPV) vertical managers for maximum capacity and seamless transition. The waterfall trough is steel and black.
