The m!ka Bushing is one of the plug-in options to attach an m!ka Arm to your desk. It can be combined with an m!ka Microphone Arm or m!ka EasyLift Monitor Arm.
Use the stainless steel bushing to attach your m!ka Arm to your desk by drilling an ø 22mm hole and securing the bushing with a washer, spring washer and nut from under your desk. Then slide in the m!ka Arm of your choice.
