It has been winter and handrails are not installed. The handrails are assembled and ready to mount on the steps. Seems to be a good product. I can understand why assembly brackets were not installed or put together at the factory, very labor intensive to put together and align the 4 holes in the bracket to the pattern for installing the screws. Had to drill out holes to allow alignment. Customer service and e-mails back and forth left a lot to be desired and a language problem. Very little instructions and many e-mails involved question as to what size of bit to use to drill holes in the concrete. Their reply - send pictures, on about the 4th try, I received information the bit size would be a 12mm. I do not plan to use the expansion bolt assembles that were sent for fear of cracking out the concrete. I will use epoxy. Customer service needs some work.
