The sign came in quickly and looks great. Its made of composite plastic and an enameled number set. Mounting is done with 2 pieces of all-thread, which isnt the most secure, but does the job. Mounting instructions are to drill 2 holes and silicone the all thread into the building. This works but is not extremely secure & has some movement if you touch it. I would suggest doing some kind of a thru bolt on the face to make the installation easier for the end user and this would also make it more secure. All in all, this does the job and we are satisfied with the address marking plate. We elected to put this directly below our front light for maximum visibility.
