      Gary was very helpful from the first and communicated with me on his on time. He was in touch with me for several days and was very helpful finding the part I needed although I did not have a picture of the part. Gary went way above what was expected in trying to find the part I needed. When we need more parts for our church doors I will definitely call Gary.

      If you need help figuring out what to do or how to do it … These people will help you make it happen. In my case it was a hardware issue and I wasn’t sure where to start. After my initial contact and a couple of pictures they were able to solve my issue … and it wasn’t even their product … Wow, these people go above and beyond. Thanks Derek !!!
