A gusset connector plate for anchoring a safety line to a roof truss, a roof truss and an anchoring system incorporating the same. The plate is substantially planar and includes an attachment region and an anchor portion. Teeth extend from the attachment region and into the sides of truss members that form the peak of the roof truss. The anchor portion extends laterally beneath the peak and a hole defined therein receives the connector for the security line. The hole is disposed below the lower surfaces of the truss members and vertically beneath the peak. The plate is permanently engaged with the truss. A single plate or a pair of plates may be incorporated in the roof truss and utilized in the anchoring system.
