40" HEIGHT SECTIONS: Easier to handle and less prone to shipping damage than full-length channels This four-channel package provides two complete 40" cable management sets for installers building out larger rack layouts or joining distribution racks together. Each channel includes pre-installed, adjustable flat mounting brackets that support side-mounting or center-mounting between racks. The front latch gate opens to allow cable feed-through and closes to hold cables in place. All channels include snap-on ABS covers to conceal cables and maintain a clean, professional look. The 40" height reduces the risk of freight damage and makes each piece easier to move, lift, and install compared to tall single-piece channels. This package includes four metal channels and four matching covers.
