This is Knobbles and Bobbles' small 25mm iron ball shaped knob.
This knob will protrude by about 35mm from your furniture.
All necessary fittings are provided. The bolt will allow for fitting to furniture that is 20mm thick. If your furniture is thinner you might need to put a spacer on the bolt, or cut it to length. If your furniture is thicker, you might need to source a longer bolt. We don't have any longer bolts, sorry.
Please contact us with any questions. Lucy@knobblesandbobbles.com
