I am attaching a video with the convex hull for your reference.

i want my hook to hang from the above horizontal bar

I'd also like to mention the option of using SDFs (https://github.com/google-deepmind/mujoco/tree/main/plugin/sdf)

Another alternative is disabling collisions for your mesh, and manually or procedurally fitting invisible collision primitives. You can use replicate If your hook part has a region of constant curvature.

If you need something quick, and for only this model, then the collision primitive method may be the fastest. (And may give you better contacts than with a decomposed mesh!)

Also I never used it for this purpose, but I think rigid flex bodies can be used for this as well?
