>>867542no cage because there's a cable safety... looks like there's one on the pegs too (which is kind of unusual).
Secure your cable climber to the cable, carabiner between that and your harness.
Climber drags up the cable as you ascend, but locks if you pull downwards on it.
Grab it and slide it upwards, then you can sit back in your harness and take a break as you climb.
Can still use a double tie off lanyard (that's what's usually done on pegs), just a little more time-consuming for 100% tie-off as you climb.... which is why the pro guys "free climb" then tie off to take a break.
Hard hat/helmet if you're on the ground under someone working at height.
