A multi-directional, equalizer clamp device is disclosed that provides, via a single action, a way to lock multiple objects that may be disposed in different numerous directions. The clamp may also achieve clamping using numerous force factors, and may be configured to attach and secure objects, such as pins, to the side rail of a support and/or operating table via a single-point of operation. The clamp device comprises upper and lower body portions which are configured to clamp to a side rail along a primary clamping direction, and are further configured to receive objects and clamp them along a secondary clamping direction. The clamp device further comprises a control assembly, such as a knob, to facilitate and achieve simultaneous clamping along both primary and secondary clamping directions at a single point of control.
