Pro-Tip from Our Locksmiths: Three-point latch devices like the 9857 give you the security of a multipoint lock on an exit device. The rim latch handles the primary latching while top and bottom bolts prevent door warping and forced entry. If the customer needs SCIF-level security on an exit door, this is what you spec.
