Hi my name is Lester Davis from USA. Roof anchors are essential components of fall protection systems that are designed to prevent workers from falling from rooftops or other elevated surfaces. Roof anchors for fall protection can be permanent or temporary, depending on the application and the type of work being performed. Permanent anchors are typically installed during the construction phase, and are designed to last the life of the building. Temporary anchors, on the other hand, are designed for short-term use during maintenance, repair, or construction activities.
