Description
4″ Welded Disc Polyurethane Wheel. Shown in photo with 5″ wheel and Grip Ring Stem. Other Stems available – Please select one from the options. This 3A stem caster is our stainless steel total locking institutional caster which uses the same Model 3 1-¼” wide wheels. A total lock brake locks the swivel and the wheel. It latches them simultaneously by one foot on the brake pedal. The plate caster swivel model 3A has a metal total lock pedal. It is simple to turn on but not as simple to let go as the nylon brake pedal featured on K3. The metal lock can only be reached if the release deise with the type of your shoe which may not allow enough burden to be utilized to unlock the brake. This is not an issue with the nylon brake pedal on model k3. The metal total lock brake pedal is an option on 3a swivels. The metal pedal is shown slightly under the mounting plate of the swivel caster and slightly over the wheel. The metal pedal extends behind the wheel so the toe of your foot can simply reach the activation pedal. The metal pedal burrows into polyurethane and rubber tires more than the nylon pedal. The amount of the metal pedal total lock brake is more than the cost of a total lock brake with a nylon pedal. Neither type of total lock brake are possible on a caster rigid.
