A 5U high by 1U wide (222.25x44.45mm) 3mm thick high grade 5251 H22 aluminium back panel for use with our matching Dual Ring Modulator laser engraved front panel. We manufacture these panels in-house on our CNC router and are supplied ready for use. The panel is also pre-tapped with fixing holes for our 'L' brackets for attaching the Acrylic PCB Holder.
The 3mm thickness + the 1.5mm thickness of the engraved front panel is optimum when used with our sockets, pots, switches and knobs as it minimises any exposed threads.
