We take a look at a Total Lock locking caster and discuss how the mechanism functions. The model used for demonstration is a Series #20 light to medium duty Total Lock with thermoplastic rubber tread wheel. When the foot switch is depressed, a tread lock engages the wheel and three prongs become inserted into the crenelated lower raceway. This action brakes the wheel and locks the swivel to create a stationary, non-swiveling, locking caster.
