I installed (exchanged) at a height of 3 m from the ground but I was satisfied with good visibility. As always, I was left to the trader, but I exchanged myself and I was able to reduce expenses. I selected it in the net catalog, I understood the size, design, specifications very well. This month, there was on-site inspection of the administration and it was saved because we could exchange in advance. Simple drip-proof ... installed outside, was it okay with this? For the first time, amateur I searched ... Knowledge-free I was able to select Net catalog easy to understand It was partly corresponded with old parts, installation completed.
