The walls into which the section is to be mounted should be finished and painted.

First of all, you have to aluminum cutting and drilling the necessary measures, calculating a separation between two fixations, taking care that the position of the anchors should never be front of each other because the wall is weakened. This model does not have a end bit, since being variable angle is impossible to do it, for this reason, and to avoid the accumulation of dirt, NOT recommend installing the model at less than 2 meter tall height.
