Corbin Russwin 688F17-7 Latchbolt - For ML2000 Series Mortise Locks

The Corbin Russwin 688F17-7 is a genuine OEM Replacement Latchbolt designed specifically for the ML2000 Series Mortise Lock. As the primary locking element of the door, this latchbolt features an integrated anti-friction tongue that ensures a smooth, quiet transition into the strike plate. Engineered for Grade 1 high-traffic applications, the 688F17-7 provides the structural strength required to maintain life-safety standards and building security in the most demanding environments.

Institutional Grade Features

• ML2000 Series Precision: The factory-authorized replacement latch for the entire ML2000 mortise line, ensuring 100% compatibility with the internal timing and retraction mechanics of the lock case.
• Anti-Friction Design: Features a specialized insert that reduces wear on both the latch and the strike plate, preventing the "binding" or "sticking" common in heavy-duty commercial doors.
• Deadlocking Security: When the door is closed, the auxiliary bolt (deadlocking plunger) works in tandem with the 688F17-7 to prevent "loiding" or unauthorized retraction via credit card or shimming tools.
• Field Reversible: Designed to accommodate various door handings, allowing for seamless installation in Right Hand, Left Hand, or Reverse configurations.
• High-Strength Stainless Steel: Manufactured to resist the intense shear forces and daily impact cycles typical of schools, hospitals, and municipal buildings.
