Hi All, I need to get up to the eaves at the rear of this 2 story house which I measure at 8 meters tall. I'm guessing I'll need a 9 meter extension ladder. Is there such a thing? I had a look on ebay and long ones there are around the 5 meter mark which I already have? It's a one off job, so a rental will be the go I guess, if they exist.
