Exactly what I was looking for. I bought three brake, heater, and alternate air fir myRV-7A. We’ll constructed and smooth as butter. The locking mechanism is firm providing positive control. The only downside is the microscopic BB that makes it all work. There are two extra in the package when you inevitably loose one.
