I'm only on the installation side but I know that they are one of the largest door hardware companies in the world.

I couldn't tell you how it goes down at corporate HQ and I don't want to know, but every representative I've dealt with in the field has gone the extra mile for me to make my job easier.
They are a spin off from ingersoll-rand and have been in this business since before I was born. She could do worse.
