These wheels take the HF toolbox from crazy to silky smooth. They are a direct replacement for the included 5 inch casters. Great value for money and the locks are the most comfortable I've ever used. I will use them to upgrade store fixtures.
Pros
★Heavy Duty (Load Capacity): One wheel can bear 330lbs, four wheels can bear more than 1300lbs, double ball bearings, easy to press, save labor.
