Looks like a 795 36" balancer

It looks very much like the 795 balancer with a 36" x 1/2 x 9/16 channel except the plastic pivot shoe on mine is only 1" wide and yours show a width of 1 1/4. I could probably cut that down to fit but wondered if there is another pivot shoe that is 1"wide?

Yes, as a matter of fact there is! Looks like you need a Series 795 channel balance with a 15-194 pivot shoe. You can just snap the standard shoe off and snap this smaller shoe on in its place.
However, it also looks like you have a special clip at the end of your cord. The Series 795 comes with a different kind of clip that mounts with a screw, not as a hook. We carry the 15-198, which should work for you, but installing it on the Series 795 would require re-knotting the cord, which can be tricky. If you aren't confident with that then we can make it for you.
