ten inches to allow rack 10 to fit within spaces in narrower than existing racks 0030 fig1 a shows a schematic of an existing telecommunications installation including a first existing rack 100 a second existing rack 102 and a third existing rack 104 arranged in a row racks 100 102 and 104 may be standardized widths of nineteen or twenty three inches or may be some other non standard width racks such as racks 100 102 and 104 may include a pair of vertical supports and define a plurality of mounting spaces between the supports for mounting telecommunications devices racks 100 102 and 104 are mounted adjacent to one another but a gap 106 and a gap 108 are left between the adjacent racks often to provide space extending telecommunications cables extending to from and between the devices mounted to racks 100 102 and 104 gaps 106 and 108 may be considerably narrower than the width of racks 100 102 or 104 often gaps 106 or 108 are between six and eight inches in width much too narrower for existing racks such as 100 102 or 104 to be installed the devices mounted to the racks may be optical fiber devices so that the cables in gaps 106 and 108 are optical fiber cables or the devices may be used with copper.
