The Hammond RM3UMTGFL is a replacement front pair of rack ears, the 3U rack-mounting flange for RM Series rack-mount aluminum instrument enclosures. It serves builders and technicians who need to replace lost or damaged ears, or to add rack mounting to an RM enclosure that ships without them.
The RM3U0808SBK and RM3U0808VBK half-width drawings note that the mounting flange is not included and list "MTG. Flange w/ Screws RM3UMTGFL" as the accessory, so this pair is how those 3U cases gain flange mounting. Per the series sheet, the flanges include enclosure mounting screws.
The flange is aluminum in black. Its drawing shows a 132.59 mm [5.220 in] flange height, matching the 3U enclosure height on the drawings, with 120.65 mm [4.750 in] between the two 0.422 x 0.250 rack slots. The material is 3.18 mm [0.125 in] thick, and two 3.99 mm [0.157 in] holes countersunk at 82 degrees attach it to the enclosure.
It is sold as a replacement pair for the 3U height only; the RM Series lists separate RM1UMTGFL, RM2UMTGFL, RM4UMTGFL and RM5UMTGFL flanges for other heights.
RM3UMTGFL is RoHS and REACH compliant, ships in a box at 0.31 lbs (0.14 kg), and carries UPC 623980538679 and UNSPSC 43201602.
