Mounting
Every current-generation IgorBox controller shares the same chassis and base plate, so one mounting story covers all of them: the Output 8 MKII, Input 16, LED Controller, and IgorBox DMX.
The chassis has holes for wall-mount directly with screws through the side flanges, and we sell a DIN-rail bracket kit that can use the side flange holes to position the controller in 5 different positions.

Upgrading from earlier hardware
- From an Output 8 MKI: the MKII hole pattern matches the MKI, so your existing rack-mount, wall-mount, and DIN-rail hardware is reusable.
- From an Input 8: the Input 16 uses the same chassis dimensions, so existing brackets and racking are reusable.
