How To Order Overhead Door Holders and Stops
Overhead door holders and stops are often found in commercial buildings since they preserve the door from damage by stopping the door before it can slam into the wall. This page goes over how to properly order overhead door holders and stops for your door.Is your door fire rated?
If your door is fire rated, then at the hinge side of the door there will be a label with the fire rating. Common fire ratings include 3 hour, 2 hour, etc. Why does this matter? It matters because you do not want to void your fire rating. You will need to make sure you only install a fire rated overhead door stop on your door. If you choose not to do so, then your door will no longer meet fire code requirements, and the fire marshall will flag the door as not meeting proper fire code.Concealed Vs.
