Fifteen grades are identified for differing applications \u2013 hinged or sliding doors with rim or mortice locks with either keyless egress from inside or key locking from both sides. The grading determines which application is appropriate. In addition, there is a requirement that lock\/latch should not be removable from outside or, for grades K to R, from inside using \u201cstandard\u201d tools. Grades H and P require support for the lockcase when installed.<\/p>\n\n\t<\/div>\n\n\n\n
