This brand new type of control has all the fine adjustment benefits of an old style push-button release vernier control, with the simplicity, responsiveness and jam-proof safety of a friction lock control.

These light weight controls use a patented roller action and do not use a positive lock thread engagement. Coarse adjustments are made by pushing the knob inwards or pulling the knob outwards. Fine adjustments are made by rotating the knob clockwise or counterclockwise. For extreme conduit routing or heavy carburetor load installation, slight inward or outward assist pressure could be required during rotation.

We currently offer these controls for use on non-certified aircraft only. However, we plan to obtain FAA-PMA approval to offer the Vernier-AssistTM mechanism as an option on many of our currently approved controls for Cessna and Piper.

• Light weight and compact behind the dash
• Plenty of room for your hand around the knob
• Safer – Our roller action cannot jam
• US Patent No. 8,485,057
