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.
- Fire-Rated Reliability: UL/cUL Listed for use on fire doors with ratings up to 3 hours, ensuring your facility remains compliant with strict life safety codes.
- 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.
- ANSI/BHMA Grade 2 Performance: Built to meet Grade 2 standards, this latchbolt is designed to withstand hundreds of thousands of cycles in medium-to-high traffic areas.
- 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.

Professional Maintenance & Security
The Accentra MCD234 is the preferred choice for facility managers looking to restore the security of their keyed entry, classroom, or storeroom functions. When a latchbolt becomes sluggish or the deadlocking plunger fails to engage, the security of the entire opening is compromised. Replacing it with an original Accentra factory part ensures that your Grade 2 locksets continue to operate with the precision and safety intended by the manufacturer.
For interior doors that do not require deadlocking security, such as passage or privacy sets, the plain latchbolt version (MCP234) is also available at DoorwaysPlus.com.
