Roto Frank of North America's HPD1 is a hinged patio door locking system. This locking system supports taller doors between six feet and ten feet in height and includes three kinds of active locking points: 3-point tongues, 3-point shootbolts, and 5-point tongues and shootbolts. It comes with 35 or 45mm backsets with a 60mm backset under development, a one inch deadbolt and a reversible mishandling device to prevent damage to the door frame. It passed the AAMA 909 cycle test and the AAMA 1304-02 voluntary specification for determining forced entry resistance of side-hinged door systems.
