Good quality and not too difficult to install. A little modification was needed to cover old hardware notches; push bar & handle work great, and do exactly what they were supposed to do.
We were required to change the door handle from a standard handle to a panic bar. This one was super easy to install. I watched a YouTube video, and that gave me some confidence. Install was simple and took about 30 minutes.
I installed this on an exit gate from the rear deck we built for a bar. Arrived on time, was easy to install and works well. It was very easy to trim the length down to fit the gate. Can not speak to the longevity yet.
