Abstract: A workbench with an adjustable height top dually engaged by twin standards with each standard having a single pawl-like structure laterally extended from front to back. The pawl mechanism in each standard is a laterally extended round rod engaging a vertical array of rounded ratchet apertures at the front and back end of the top. A novel safety mechanism to prevent inadvertent disengagement of the rod from the ratchet apertures is a combination of a tension spring connected between a chain and a foot actuator pedal. This spring prevents accidental release of the rod by absorbing unintentional or inadvertent minor force applied to the pedal. The rod-like structure or pawl provides superior structural rigidity for the bench when restricted with rear shims to rotation into the ratchet slots at an angle &agr; between less than about 45 degrees and greater than about 10 degrees.
