The Double Clamp Mount Boom Screw is a mount accessory and is manufactured from non-conductive material to minimise RF influence.

This device has been engineered for gripping the various clamps that sit on mast booms. It screws into the standard heavy duty clamps such as items 845 DCM-A2 HD Heavy Duty Double Clamp Boom Mount, and the DCM-A4 from the other side of the standard 5.2cm mast boom.
