  • Safe and Secure Door Plate

The door plate, in conjunction with a doorjamb, makes one strong unit. The door plate wraps the vulnerable area of the doorjamb with its steel property thus becomes more impervious to splitting the edge of the doorjamb or any part of the protected area of the wrapping.
