[RE-wrenches] Anyone recognize this pole mount system?

[David Katz]

Timothy,
They are definitely NOT Tamarack.  I doubt you can bring them up to code.
Current code is 115 MPH.  Tamarack is currently working on certified
engineering on their pole mounts for up to 150 MPH wind and up to 50 PSF of
snow load. I can see that the one on the orange pole is not going to make
an engineer happy.  That one definitely looks home made.
