Set of 4 x 40mm Braked castors complete with 8mm screw in pin
Being a braked castor means you can lock each castor thus preventing movement of cage.
This braked castor is now supplied with all new stands and racks
The pin on the castor has an 8mm thread so is not suitable for some of my older stands and racks supplied years ago.
Please be sure if ordering that your stand or rack has an 8mm thread and NOT 10mm as years ago.
