Frequently Asked Questions

Why choose 5-inch over 4-inch stem casters? ›
5-inch wheels roll more easily over obstacles and handle higher loads (350 lb vs 300 lb per caster). They are ideal for heavier shelving units.
Can I upgrade from 4-inch to 5-inch on the same rack? ›
Yes, if the threaded stem size matches. The 5-inch wheel adds about 1 inch of overall height.
Are these good for wire shelving? ›
Yes. Threaded stem casters are the standard mount type for wire shelving systems like Metro, Regency, and similar brands.
