This is a metal bar that is installed vertically in front of a Cessna radio stack and locks to the left and right control yoke columns. It requires two bicycle locks which are not included, I used these on 182RG and 210 aircraft. Easy to install/remove before and after flight. Don't recall why I have two, one of these is unused. $135 for the used one and $175 for the newer one, ground to continental U.S.

Thanks
