I recently purchased a set of casters for my pallet jack and was thrilled with their performance. As a result of my tests, I determined that these casters have a very smooth swivel and are ideal for moving heavy loads around my warehouse. They are also durably constructed for long-lasting use.However, the bright orange color might not be the best for those seeking a more understated look. Overall, i highly recommend these Schioppa GLEED 210 GEL casters for any industrial and scientific material handling needs..
