Audio-Technica AT8492UL Universal Clip-on Mounting System (Long)

The AT8492UL is the long-reach version of Audio-Technica's universal clip-on mounting system for the ATM350a, pairing the same rubber-lined universal clip with a 9-inch gooseneck instead of the standard 5-inch. The extra length is useful when the clamp point is further from where the capsule needs to sit, such as miking across a wider instrument or fixture.

The clip mount itself is identical to the AT8492U's, so the choice between them comes down to how much reach the mounting point requires.
