This is a used Condor universal E track adapter. This mounts to two strips of etrack and then you mount your Condor chock to it. It will hold any Condor chock. There is 3 "tabs" that you bolt to your condor. The end mounts are a bit flexible so you don't have to have perfectly aligned track to have it work. It goes down to 29 inches on center ( to the track) and expands to 46 inches (while still "together" well).
It is used and there is some wear but functions well. I do have a few of them if you wanted more than one.
