The wheels featured with Caster Model K3A are non-marking. 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.

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!

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.

Total Lock Brake On

Total Lock Brake Off

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.

Swivel Radius for Casters with the Total-Lock Brake – ALL SIZES – 5″

Approximate Weights – Swivel Caster with ML Brake – 3″ wheel = 1 3/4 lbs. – 4″ wheel = 2 lbs. – 5″ wheel = 2 1/2 lbs.

Typical Application Use for the Total Locking Caster Model 3A Series:

img Workbenches
img Shop Equipment
img Kitchen Islands
img Movie & Soundstage Equipment
img Hospital / Medical Equipment
img Computer Equipment Stands and Mobile Workstations
img Electronics & Diagnostic Equipment and Carts
img Any Application requiring the item to be held firmly in place.

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.
