outdoor is installed on racks on the wall. i took the pictures once it was not installed.
You are right the distance from roof should be more but i was in a fix since the holes in the wall were from previous installation so had to install. still its around 1 ft lower from the roof top.
Its a quality product. AL HAMD U LILLAH.
no bro no vacumm installer available in ISB & PINDI as far as i know.
