Good workmanship. Practical at the same rear wall. Here the components can easily accommodate, as the housing can be assembled later added. I find it a little disturbing that the front door has no hinge for when making adjustments to the built-in devices you must always see only what to do with the front flap. It's not easy to a high ladder with this flap because this is suspended only in the case and one so the thing has up there in his hand.
