Revolutionizing Ligature Resistance in Door Hardware
The DH425 Ligature Resistant Mortise Latch Set is built to prevent ligature points from all angles—up, down, left, right, and forward—providing optimal security and peace of mind for both staff and patients. Additional benefits include:
- 5-Point Ligature Resistance: Unique handle and trim design prevent ligature from any direction.
- ADA-Compliant Design: The handle operates with a simple downward pull, automatically returning to the up position for secure latch closure.

Durability and Versatile Functionality
- High-Quality Stainless Steel Construction: Crafted from solid stainless steel, including handle, escutcheon plate, deadlocking latch bolt, and ASA strike, all in a satin stainless steel finish.
- Wide Range of Functions: With over 25 available functions, the DH425 is adaptable to various facility needs. We recommend the passage, classroom, or privacy/bathroom functions for behavioral and psychiatric environments, as all allow free egress to meet safety and fire codes.
