Durable USA/Superior Casters has the best stainless steel kingpinless caster on the market! That’s not just an empty claim! Durable USA is the only manufacturer that makes a drop forged kingpinless caster entirely out of S302 stainless steel.

We submitted our caster, along with three of our competitors’ casters, to a 3 week corrosion test. Each caster was submerged in a salt water solution for 5 days and then removed. For the next two weeks they were sprayed with salt water, twice daily, and stored in open air.

See for yourself! Results show that Durable’s stainless steel kingpinless caster is the best available!

An independent metallurgical laboratory test also discovered that brand “A” is made with lower grade stainless steel that contains less chromium and nickel, the main corrosion resistant elements in stainless steel.
