The RM5U18BRKT is an adjustable-depth rear bracket kit for mounting 5U RM series aluminum instrument enclosures in 4-post racks. Hammond's short description is "REAR BRKT KIT FOR 5U 18" DEEP", and in the RM ordering table it appears as the Adjustable-Depth Rear (Pair) of Rack Ears for 4-Post Mounting for 5U chassis height, with a maximum depth added to the chassis of 16.00 in (406 mm).
