Mortise Hinge
The M series complies with U.S. national standard ANSI A156.17, with interlocked barrel leaves — the standard choice for spec-driven U.S. commercial projects. K / M / R share the modular spindle-core platform (B-type), with upper and lower modules linked via a square-section spindle. Any door can use the M series; because the leaves interlock, it needs the door and wall to sit flush on the same plane (a flat, 180° mount), which is why it's common in standard flat-frame offices, healthcare corridors, and classrooms.
