The 51005-CM6-42 cable manager cabinet is secured to a Datacenter rack using up to ten 1/4" bolts along the top and bottom of the cable manager.  The holes circled in red in the following diagram will line up with holes in the Datacenter rack and are used to secure the cable manager at the top and bottom of the rack.  The two locations circled in blue, are optional as some of Telect's Datacenter racks don’t have a matching hole for securing the cable manger in those locations.
