Great replacement
Direct replacement on my 2016 Mack, 4 bank of batteries... Tied my inverter into it this time. My previous switch was draining my batteries, (parasitic draw from the original quick disconnect switch)

Heavy Duty Disconnect
Purchased this for use on a New Holland self-propelled swather (H8040) that uses 2 batteries. It has power draw on it that after 1 month of sitting it would be completely discharged. Fairly easy to install, quality seems top notch. Reminder is you'll probably need at least 1 additional heavy battery cable depending on where it can be mounted... might need even a couple more, not to mention a different bracket to mount it to. I was lucky and was able to route the cables from both batteries to the switch, and had a spare cable on hand that was able to reach the starter on the machine. Going to purchase another one, might need it on another machine sometime.

Exact replacement on my 2005 Isuzu NPR.
My old switch had carbon build up and was losing ability to start my truck. I installed the new switch and it turned the engine over twice as fast. I'm very happy.
