Maximum security MS+ deadlock after hours, plus the convenience of traffic control management during the business day. Typical installation is a bank or store requiring three modes of door control:
1. Both lock and latch bolts retracted for unrestricted entry and exit during business hours
2. Handle-operated latch for exit-only traffic just after closing
3. Maximum security MS hook bolt for overnight lockup. When using trim (available separately) to activate, handle or paddle operates latch bolt only.
