Total Locking Casters – Stainless StemCaster Model 3A

Total Locking Stainless StemCaster Model 3A

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!

“You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.”

Total Locking Stainless StemCaster Model 3A Features:

Swivel Radius for Casters with the Total-Lock Brake – ALL SIZES – 4 3/8″

Use the Polyolefin ( Industrial Plastic ) wheel for “Standing Loads”. Polyolefin wheels eliminate the possiblilty of a flat spot developing if the castered equipment is left parked for a prolong period.

Threaded Stem Casters should NOT be used as a “Leveling Device”! Capacity ratings are based on the weight being directly on the top of the swivel bearing, not somewhere above it on the threaded stem. 

Total Locking Brake:

Combination Wheel Brake and Swivel Lock – This brake simultaneously locks the wheel and the swivel. One step on the activating pedal instantly locks the entire caster holding the equipment firmly in place. One step on the 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.
