Hammond RM1918BKSP 16.60 x 18.00 in Solid Top/Bottom Panel, Black

The RM1918BKSP is a solid 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 18.00 in (457 mm) deep, the full 16.60 in width footprint listed in the RM ordering table for the RM1U1918SBK through RM5U1918SBK 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 sized 16.60 in wide by 18.00 in deep for the 18 in deep full-width RM enclosures, with 8 X Ø4.30 mm thru mounting holes countersunk Ø6.00 mm x 82°.

The drawing specifies the panel material as .064" aluminum (5052-H32) with a black powder coat colour, and the part page lists aluminum material in black. Drawing dimensions show the panel at 413.80 mm [16.291 in] by 443.00 mm [17.441 in], 1.80 mm [0.071 in] thick, with mounting holes called out as 8 X Ø4.30 mm thru, countersunk Ø6.00 mm X 82.0°. Top and bottom panels in the RM design are interchangeable, so the same part serves either position.

The RM1918BKSP is RoHS and REACH compliant, has a shipping weight of 3.31 lbs (1.50 kg), and carries UPC 623980102320. 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.
