Accentra MCD234 630 Guarded Latchbolt | 2-3/4" Backset | Satin Stainless Steel

The Accentra MCD234 Guarded Latchbolt (formerly Yale) is a critical security component designed for high-traffic commercial and institutional door applications. This deadlocking latchbolt is specifically engineered for the Accentra 4600LN Series cylindrical locks, providing an essential layer of protection against unauthorized entry. Featuring a guarded latch—also known as a deadlatch plunger—this hardware prevents "shimming" or "carding" attacks by locking the main latchbolt in place when the door is closed and the auxiliary pin is depressed.

Constructed from heavy-duty materials with a 630 Satin Stainless Steel finish, the MCD234 offers superior corrosion resistance and long-term durability. Its 2-3/4" backset and square corner faceplate make it a standard choice for new installations or as a high-security replacement for worn components in offices, schools, and healthcare facilities.

High-Security Commercial Engineering

• Deadlocking Protection: The integrated auxiliary deadlatch plunger ensures that once the door is latched, the main bolt cannot be retracted by external pressure or manipulation tools.
  
• Premium 630 Finish: The Satin Stainless Steel (US32D) finish is not just aesthetic; it provides an industrial-grade barrier against moisture and wear, maintaining its appearance in harsh environments.
• Seamless Compatibility: Specifically manufactured as a direct replacement part for Accentra (Yale) 4600(LN) and 4600YC series cylindrical lever and knob locks.
  
• Installation Ready: Shipped with a 1/8" sleeve (P/N 14-0378-9001) to ensure a perfect fit in standard 1" door preparations.
