It’s hard to do, and I’ll admit it took me a few tries to get it right. You’re able to actually hook up into the vent through the control room without any assistance; just the hook and the right jump will let you throw it to the high side of the vent wall. When you tighten the cable you’ll bob outside the vent, but if you crouch and hold spacebar (at least that’s how mantling worked for me) you’ll be able to pull into the vent at the right moment.
It’s a struggle but certainly possible.
