Based on my experience with this industrial and scientific caster, it is a high-quality product that is perfect for any material handling job. The threaded design ENSURES a tight fit to the furniture, preventing any wobbling or movement during transportation .The lockable feature keeps everything secure during storage eliminating the risk of damage or injury. The only downside is that the price is a bit steep compared to other casters on the market. However, the peace of mind and durability this product provides makes it worth the investment..
