Having additional Silver Bullet Lids with different port configuration adds flexibility to your vacuum on the job. Choose between 1 or 2 port lid configurations and 2″ or 2.5″ diameter vacuum hose ports.
If you are purchasing a dual 2″ port lid you may consider adding a 2″ Port Plug to your order for convenience and added flexibility.
Rear Lid Disclaimer
Think twice about installing a different rear lid. It’s not easy. I don’t recommend you do it.
If you do decide to do it, you are on your own.
