No. The SB57163D096TG is a 96 inch tall section, built to run the full height of a 8-foot open frame rack. On an 84 inch rack it would overhang by a foot. For a 7-foot rack you need the 84 inch version of the vertical cabling section instead.

Yes. The section is a dual hinging, removable design, so the cover swings open from either side for adding or re-dressing cable, and the whole section can be taken off the rack when you need clear access. That is the practical difference from a fixed finger duct.

Aluminum, finished in Telco gray powder coat. The grey powder coat is the standard telecom shade, so it matches Telco gray open frame racks and adjacent sections in the same room.

Use both for different runs. This B-Line section mounts to the side of the rack and carries cable vertically between the top of the frame and the equipment rows, which is where bundle volume builds up in patch fields. Horizontal managers only handle the short slack between a patch panel and the switch directly above or below it. If you are landing more than a couple of panels on an 8-foot frame, the vertical section is what keeps the bundles off the rails.
