The Ultimate Phenolic Wheels for Your Tool Boxes & Tool Carts

Weight Capacity: An Astonishing Range from 700 to 1,250 lbs Per Caster

Why Phenolic Wheels from CasterHQ are Nonpareil

When it comes to combining durability, capacity, and maneuverability, no other caster wheel does it better than our Phenolic Wheels. Manufactured through a high-pressure molding process of phenolic resin and macerated canvas, these wheels are robust, lightweight, and built to last. They are designed to resist oils, greases, and mild acids, ensuring you a hassle-free experience no matter where you use them. Compare with Gray Iron Wheel Casters.

Where Can You Use These Wheels?

These versatile wheels are perfect for heavy-duty applications in warehouses, automotive garages, and retail environments. Their smooth rolling action makes it easy to move your toolboxes and carts across concrete floors without damaging the surface. Learn more about Phenolic Wheels.
