The 2090 Series is a two station mechanical control system, with one head acting as a master control and one as a remote control. Both controls work in tandem, moving at the same time to sync controls across multiple stations.
The 2092 / 2094 are solid bronze and stainless steel control heads that can be used for twin engine configurations, with one handle for clutch and one handle for throttle. The 2092 has a pull-out handle for over-riding throttle, and has separate handles for clutch and throttle.
The 2092 maximum clutch stroke is 2 3/4" (70mm) and maximum throttle stroke is 2 1/4" (57mm), and requires a cable connection kit that typically uses 30 Series or 40 Series cables.
