The Albion casters are a game-changer when it comes to material handling products .As a result of my tests, I determined that their polyurethane precision casters provide optimum maneuverability and durability for my lab equipment. The quality of the materials is evident, and I appreciate the attention to detail in their design. The only downside is they're a bit pricey compared to other casters on the market. Overall, I highly recommend these casters for industrial and scientific applications..
