All of these Thomas Vox amp heads have a threaded "tee nut" on the inside lower panel of their cabinets that was designed to accept this steel clamp and wingbolt. Installable in under 15 seconds, this accurate reproduction of the original Vox clamp will firmly secure your precious vintage Thomas Vox amp head to the stand so that it cannot fall off the trolley. You need make no modifications to a Thomas amp head to use this clamp.
Like the originals, the head clamp is finished in a dark gray/black zinc oxide finish that will not rust.
This head clamp will also work with any of the North Coast Music trolleys for Vox amps, such as the Beatle, Royal Guardsman, and Buckingham.
This clamp is designed to only fit on trolleys that have about a 7" space between the tubes. For this reason, it will not work with the Berkeley, Cambridge, Pathfinder, or Pacemaker series of amps.
