Why Seat Mounting Matters: A Quick Look at Hardware Differences
This is how we design our mounts to work—with the scheel-mann seat’s mounting boss (the six round metal posts under each seat) dropping into a precision-cut hole. We supply a custom flange bolt that holds everything together from the top. In this setup, the mount carries the side-to-side forces, not the bolt.
