This is a two-piece copper cover for the typical 1" diameter commercial door push bar. The 24" length will cover the highly used area of the bar. As with all our items, this is 99+% pure copper without any coating, so it will have a bright copper beauty when you install it, and will naturally develop a beautiful patina with time. It ships with permanent mounting tape already installed, just peel and stick on your existing door hardware for a quick transition to a safer touch point in your building.
