Hammond RM1928BKVP 16.60 x 28.00 in Vented Top/Bottom Panel, Black

The RM1928BKVP is a vented replacement top or bottom body panel for the RM series rack-mount aluminum instrument enclosure, sold individually. Its nominal panel size is 16.60 in (422 mm) wide by 28.00 in (711 mm) deep, the full 16.60 in width footprint listed in the RM ordering table for the RM1U1928VBK through RM5U1928VBK enclosures. It is intended for OEM builders, maintenance teams and integrators who need to replace a damaged panel, keep a spare for machining, or change an enclosure between solid and vented tops.

It is the largest vented panel in the series; its drawing shows 816 perforations of 0.177 in in 17 rows by 48 columns on 0.313 in x 0.313 in spacing, over a 16.60 x 28.00 in panel.

The part page lists the material as aluminum and the colour as black; the RM series specification describes the top and bottom panels as flat aluminum 0.064 in (1.6 mm) thick. Drawing dimensions show the panel at 413.79 mm [16.291 in] by 697.00 mm [27.441 in], 1.80 mm [0.071 in] thick, with mounting holes called out as 12 X 0.160 in thru, countersunk 0.256 in X 82°. Top and bottom panels in the RM design are interchangeable, so the same part serves either position.

The RM1928BKVP is RoHS and REACH compliant, has a shipping weight of 3.31 lbs (1.50 kg), and carries UPC 623980574486. The drawing notes that the panel can be factory modified (milling, drilling, printing) and that solid models are available in STEP or IGES, useful when planning cut-outs for connectors, fans or displays. Because RM enclosure panels are powder coated, they are not grounded to the frame; the grounding method is to be determined by the customer.
