The Alpha swivel castor with total lock features a rectangular plate fitting and a housing made of heavy steel sheet. It has two ball races for the swivel bearing. The wheel body is made of sheet steel with a solid rubber tread in black that is electric-conductive. The wheel uses a roller bearing and has a diameter of 4.92 inches. The overall height of the castor is 6.1 inches. It has a load capacity of 220.46 pounds at 4 km/h and a static load capacity of 440.92 pounds. The total lock functionality allows the castor to be locked in place and prevent swiveling. The rectangular plate fitting provides a sturdy connection point to mount the castor. The heavy steel construction ensures durability, while the conductive rubber tread prevents static buildup. With its high load capacities and total lock feature, the Alpha castor is an ideal heavy-duty swivel castor.
