Choosing the Wrong Industrial Caster Is an Expensive Mistake

An under-rated caster fails prematurely and damages equipment. An over-rated caster costs more than necessary and may not fit your floor type. A wrong tread material leaves marks, scratches surfaces, or fails in wet or chemical environments.

At Douglas Equipment, we've been specifying the right caster for the right application since 1955. As Colson's Master Distributor in Florida — backed by Blickle, Durable Superior, Darnell-Rose, P&H, and Casters in Motion — we carry the largest in-stock caster selection in the state.

Caster load ratings must include a safety factor appropriate for the application — typically a 1.25× multiplier on the per-caster load. Our team applies this standard on every specification, so you don't have to.

If you need a specific certification (medical, food contact, ESD, marine, etc.), we request the documentation directly from the manufacturer we represent — or we can point you to their published reference. Certifications are issued by the brand, not by Douglas.

The Six Specification Variables

1. Load Capacity. Per-caster minimum = (total load) ÷ (number of casters) × 1.25 safety factor.
2. Wheel Tread Material. The most application-specific variable.
3. Mounting Type. Plate, threaded stem, grip ring stem, grip neck stem, square stem, expanding adapter, pipe thread, and other options.
4. Swivel vs. Rigid Configuration. Standard: 2 swivel + 2 rigid at opposite corners.
5. Brake Type. Side-lock, top-lock, or total-lock for medical environments.
6. Environmental Factors. Temperature, moisture, chemicals, ESD, regulatory compliance (we request manufacturer certs as needed).
