The Fastronix 303-001 battery disconnect switch is made to be installed through a panel but that doesn't fit every need. With the Fastronix all aluminum mount, you can use the preferred Fastronix 303-001 battery switch in any location! Featuring a black annodized frame to match the face plate and 1/4" mounting holes to accomodate screws, or bolts. To install, remove the two allen screws on the clamp and remove the outside of the clamp. Install the bar at your preferred surface, install the Fastronix 303-001 switch in the desired position, and reinstall the clamp. It's easy!
