hey , we ordered the cb6000s device so i looked online for instructions and i did not understand the purpose of the spacers , from what i have seen they slide befor the cage and then comes the lock. now wouldn't the cage will slide up all the way to the lock regardless of the spacer?
The spacer goes from the back ring to the cage; to fit you more closer to your size, the lock goes on last, and holds everything tight, no slipping. Rae
