Total Locking Casters - Caster Model 3A - Plate Mount
Capacity up to 300 pounds per caster.
These institutional casters are ideal for any light duty application where the caster must be totally immobile when the caster brake is applied. Caster Model 3A has a unique brake which locks both the wheel and the swivel bearing at the same time. This "Total-Lock" brake insures that the swivel caster will not turn when the wheel is locked. This combination wheel brake and swivel lock is essential for safety in some applications - such as on worktables, tablesaws, and medical equipment. The Total-Lock brake is desireable whenever a brake is needed because it makes a swivel caster totally immobile. The wheels featured with Caster Model 3A are non-marking. Gray Soft Rubber and Polyurethane wheels have a sealed precision ball bearing. They provide floor and cargo protection, quiet operation, and are very easy rolling. Try a set of 4 casters. You will be amazed at their performance!
Mounting Plate - 2 3/8" x 3 5/8"
We suggest that you do NOT drill the mounting holes to attach the casters until you receive them.
We do NOT include mounting Hardware.

  • Combination Wheel Brake and Swivel Lock - This brake simultaneously locks the wheel and the swivel. One step on the metal activating pedal instantly locks the entire caster holding the equipment firmly in place. One step on the metal release pedal frees the swivel and wheel.
We offer a Black Nylon Pedal for those that need an easier to activate and release Total Lock Brake. Click Here.

- Swivel Radius for Casters with the Total-Lock Brake - ALL SIZES - 4 1/2"
Approximate Weights - Swivel Caster with ML Brake - 3" wheel = 1 3/4 lbs. - 4" wheel = 2 lbs. - 5" wheel = 2 1/2 lbs.

Use the Polyolefin ( Industrial Plastic ) wheel for "Standing Loads". Polyolefin wheels eliminate the possiblilty of a flat spot developing on the surfiace of polyurethane and rubber tires when the weight exceeds 2/3 of the rated capacity when the object is left parked most of the time .

You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these casters are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application.
