The BOSS 21"

[patricemougeot]

Does the BOSS 21" have the option of a 3" backing plate?

No the long throw machines use a 5 or 6 size bp. Due to the increased throw etc it wouldn't be recommended to attempt such a thing. The rules mini is a 3in unit with a sizable 12mm of throw however. Griots makes a 3in polisher but the throw is 8mm and lacks the power of the rupes

No. only the 5" (from the G15) and the 6" it comes with.
