  • Good almost perfect.
Size: Universal Siding Mounting Block
First thing you need to know about these is that the hole is exactly 4 in. So anything that you plan to mount to this needs to be a little bigger than the 4 in. I was trying to use a lighting cover and went to the big box store but everything that they had would just teeter-totter in the hole. I searched around and the only one I could find is the RAB c100 which works great. The only other thing is that if you are planning to mount anything heavy on this I would plan on drilling into your substructure. It's solid enough. It's the only thing I can find on Amazon that really works like this so I have bought it numerous times. ... show more
