FAQ
What is the Total Locking Plate Caster Model K3A with Polyurethane on Polyolefin Wheel, and what’s it used for?
The Total Locking Plate Caster Model K3A with Polyurethane on Polyolefin Wheel is our zinc-plated institutional caster, a light duty industrial caster shipped from Texas, Ohio, or Washington, designed for manually moved applications where cargo needs to remain stationary, with a capacity of up to 350 lbs per caster (250 lbs for 3” wheel, 275 lbs for 4” wheel, 300 lbs for 5” wheel), allowing up to 1200 lbs on a set of four.
