The 40-T2MR006 is a pair of heavy-duty steel L-Style rack rails for the left and right side of a TigerShark2 computer cabinet. The rails use a 3/8" deep square-hole pattern, and are full cabinet height, allowing users to take advantage of 42 rack units.

Single and double hash markers indicate where computer products should be mounted so they are even in the rails. The rails allow for direct mounting of SharkRack and Sun rack-mount kits with a minimum of screws required for installation.
