Abstract: A universal clamp including a first jaw, a guide, a fixed jaw, an adjustment mechanism, and a coupler. The first jaw has a first clamping face. The guide is coupled to the first jaw. The second jaw has a second clamping face. The second jaw is adjustably connected to the guide to move relative to the first jaw with the first clamping face oriented to face the second clamping face. The adjustment mechanism adjusts and secures the first jaw relative to the second jaw. The coupler is connected to at least one of the first jaw and the second jaw. The coupler is configured to facilitate attachment of a structure to the universal clamp.
