Product Overview
The Meyer Sound Thread Reducer M20 to M8 (35 mm) is a rigging adapter that converts the built-in M20 pole-mount threads of an ULTRA-X40 or ULTRA-X42 loudspeaker cabinet to M8 size. It is required when installing the MUB-X40 U-Bracket or when fitting an MTC-X40 Top Channel or eye bolts at the bottom of a cabinet. This component is part of Meyer Sound's ULTRA-X40 rigging accessory range.
Product Description

The kit includes a 35 mm diameter M20-to-M8 thread-size adapter that threads into the cabinet's integral pole-mount receptacle. One unit is already included with the MUB-X40 U-Bracket kit; this standalone item covers installations using the MTC-X40 Top Channel or eye bolts at the bottom of a cabinet, where a reducer is not otherwise supplied. It is compatible with both the ULTRA-X40 and ULTRA-X42 loudspeakers. Additional Meyer Sound products are available in the Meyer Sound collection.
