Filters Explained

Caster TypeThis is the most basic classification of casters. Do you want a caster that can Swivel, easily able to rotate to change direction; or do you want a caster that is Rigid, only capable of moving in a straight line?
Wheel Diameter
Wheel Diameter
Wheel Diameter is the measurement of the distance across the central-most point of the wheel. This is one of the most commonly used measurements for casters.
Tread Width
Wheel Diameter
Tread Width is the measurement of how wide the caster tread is. You can find this measurement looking at the rolling surface of the wheel. This is another commonly used caster measurement.
BrakeDo you require integrated capability to be able to prevent caster movement? Brakes are ideal for loading/unloading on uneven surfaces. Choose Yes to view only casters which are automatically paired with a brake.
FeaturesHere, pick among caster elements which may enhance performance (floor protective, thread guards) or reflect their manufacturing process (USA-Made, Stainless). Different caster needs may require various features. Browse these offerings as needed.
Fastening TypeHow the caster attaches to the product. For replacement casters, you will want to match the fastening type to your existing project. Learn more about fastening types in our glossary.
Fastening SizeThese common measurements indicate the available sizes of the chosen fastening option. Filter Fastening Type to reduce available Fastening Size options.
Wheel TypeThis indicates common wheel tread materials. Learn more benefits of each wheel type and find additional industry names for each in our glossary.
CapacityCapacity indicates the approved load rating per caster in pounds. It is recommended that you build a safety buffer when picking load rating. Ensuring your casters can hold more than the intended load will prevent unnecessary failure.
FinishAvailable caster finishes. Select from options including (not limited to): Stainless Steel, Chrome, Zinc and various decorative finishes.
PriceAvailable price range per casters. This reflects the single unit price. Casters may have discounted pricing at large quantities. Please see individual caster product pages for details.
