  • Metal ball castor complete with an expanding socket to suit your tube dimensions within the specified range - see product specifications.
  • Expanding sockets work with a range of tube dimensions, so you don't need to search for an exact match.
  • The castor's threaded stem screws into the expanding socket nut.
  • The swivelling functionality of the castor wheel enables furniture to be pushed and pulled in any direction.
  • Caford's metal ball castors come in either left or right-hand options. When the correct left and right-hand castor wheels are in the proper layout, they provide accurate 
    • manoeuvrability along straight hallways and around bends.
  • Wheel diameter: 50mm
  • Wheel type: metal ball castor
  • Mount height: 60mm
  • Swivel radius: 42mm
  • Fitting: 3/8 UNF x 50mm Expanding Fitting
    • 25mm of the castor's pintle stem is threaded so that the castor screws into the expanding socket nut.
  • Socket: refer to the 'Option' selection list above
  • Load capacity: 30kg per castor
    • Work out the weight of your furniture, including any contents, to determine your required load capacity. Then, divide the total weight of your furniture and contents by the individual weight capacity of the castors you plan to use. A 150-kilogram unit requires a minimum of five 30-kilogram maximum capacity castor wheels.
  • Important note: the 3/8 UNF is a fine-pitch thread with more threads per inch; it will not work with the 3/8 BSW.
