There are 3 positions of the lever on the Holland Binkley head. The position in the photo is for releasing the hitch from the kingpin. Pull the release pin and the lever will go to 90 degrees with only about half the red exposed. This is the hook-up position and the head is ready to have the kingpin backed into it. Once the kingpin is backed in fully the jaws will close around it and the lever will need to be pushed to the rear of the hitch and will lock shut. The hitch requires a little learning curve, mostly the difference between unhitch and hook-up positions.
I cant say if a bar clamp will close the hitch jaws adequately. It may need the cylindrical shape of the kingpin to work properly. I do know you want to keep your hands out of there because there is some stuff that is spring loaded.
