Enhance your chair and sofa legs by using a Brass Castor Ring or Ferrule with the Brass screw and plate style Castor. It fits at the bottom of the leg prior to fitting the Bass Castor. It also helps prevent the wooden leg splitting.
As an example - With a chair leg 1" diameter at the bottom, you need a Castor Ring size 1", this fits over the end of the leg. The Brass Castor, also 1", then screws into the leg and holds the castor ring in place.
