Adey Magnaclean Spanner. This spanner has 16 teeth. The teeth fit into the grooves on the top of your magnaclean. So if you count the grooves around the circumference of the top of your magnaclean, and there are 16 grooves this will fit your model. And by the teeth, I am on about the little square blocks around the magnaclean spanner that you can see on the image. Thanks
