Procedure

three striker plates with different bolt hole positions available for each location.
1.1 Job Set Up

across the shanks. These bolts are then installed in the nut plate as each striker plate bolt is removed.

Note

. Most frequently this will be the lower pair, nearest to the door hinge. It is
recommended not to replace more than one pair of striker plates at a time.
