This bolt-on accessory will prevent your tumbler or glass from moving laterally when rotating. Often a problem with the PiBurn rotary assembly. The adjustable stop is easy to set and very effective.
Works with anything that fits in the rotary assembly and has a flat end that the stop can press against.
Installs using the existing hardware on the PiBurn rotary. Only a 5mm allen wrench and a 13mm socket required to install.
