This arm, attached to the wall corner with a 80x80 mm angular profile with 80 cm length and welded pipe it is really great. Now I do not need more firewood to the 1st floor haul, but fill it in a specially-built transport box dimensions 100 x 60 x 50 cm and Ruck Zuck is all thanks to an electric cable line there of Guede and Einhell up on my balcony. The arm can be super swing widely, and is very stable. The assembly is easy. Good buy, I can only recommend.
