These industrial casters are made from high - quality, long - lasting polyurethane rubber. Each caster has a maximum load capacity of 50 kg (110 lbs), making them perfect for heavy - duty use. They are designed without brakes and are sold individually. The 5 - inch diameter and 1.25 - inch thickness wheels are specifically compatible with Nella Aluminum Pan and Lug Racks. Model number is 39533.

Using these casters is easy. Just attach them to your Nella Aluminum Pan and Lug Racks. You can use them for moving heavy items around, as each caster can handle up to 50 kg or 110 lbs. When using, make sure not to overload them. If you try to put more weight than 50 kg on a single caster, it may break. For maintenance, keep the wheels clean. You can use a damp cloth to wipe off any dirt or debris. Store them in a dry place when not in use to prevent the rubber from deteriorating.
