I must add my voice to a "previous speakers". Even here, an arm hanging light and the installation really needs good planning. It has not really much room to mount the support on the wall. Good measure is therefore essential, but doable. Does the awning then it is really great for the price. As mentioned before, one arm hanging also with us a little, but on request, a solution proposal we made. Does not really now helped, but in the end only also cosmetic issue and does not limit the function of the awning. For the price I would buy it again!
