How to attach the Branch

[ERP]

BTW, in the main Branch thread, a user spoke about releasing the hook under the Phantom. Can you do that? I just pulled the handle on the Branch and tried to slide the Phantom in. However, it was hard, so now I'm speculating as to whether I should have released something on the Phantom. I'm not very hooked on unconnecting it from the Branch, unless I absolutely have to, so I thought I'd ask here first.

In the other thread, someone tried to post a picture of releasing the hook, but it's not viewable.
