Round two-piece assembly for round 1" diameter crash bars. Comes with permanent mounting tape and our standard non-directional raw finish for maximum germicidal effect. 24" length. 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.
