LOL! Yes. There is a ladder on the inside that has rings behind your back, so you just lean on them as you move your hands and feet to the next rung.
The problem is that your knees bang on the rungs, and elbows catch the back rings.
So... Every 15 min there is the wording of may a nasty thought!! @#R$!! ha ha. And its not the funny bone either..
I climbed the mast on tues...same height as the one in the pic.
Got up, pulled the connector off and realised I forgot to bring the right size spanner.
Climbed all the way down and back up again....Damn was I sore the next day!!!!
