RSDT fulcrum alternatives or variations?

Are there any RSDT fulcrum alternatives for a septum stretch? It’s very difficult to find information about and I’m not even talking about pictures. I tried out RSDT fulcrum but my hanger (clamp / Bib like) for example has already height. Placing the fulcrum for leverage is difficult cause there isn’t much space left. Think it’s even impossible to hit the fulcrum this way at least in this case. Are there any variations to the RSDT?

Is this way of hanging the only way to stretch the septum? Did anyone try out doing it with a vac hanger? At least it doesn’t have a gigantic base and hitting the fulcrum should be easier? But don’t know if it’s safe enough cause of the sleeve or other reasons.

Are V-Stretches the best alternatives to it if hangers for non-hanging?

Thanks for any recommendations.
