Accentra MCD238 630 Guarded Latchbolt | 2-3/8" Backset | Satin Stainless Steel
The Accentra MCD238 Guarded Latchbolt (formerly Yale) is a high-security deadlocking component engineered specifically for the Accentra 4600LN Series cylindrical locks. This heavy-duty latch is the standard for commercial and institutional environments where security and fire safety are paramount. Featuring a 2-3/8" backset, it is the primary replacement part for doors that require a shorter latch distance than the standard 2-3/4" model.
What differentiates the MCD238 is its guarded latch mechanism. The auxiliary deadlatch plunger, when depressed by the strike plate, physically locks the main latchbolt in place. This prevents "shimming" or "loiding" attacks—commonly attempted with credit cards or similar tools—to provide a secure, tamper-resistant opening for offices, classrooms, and storerooms.
Enhanced Commercial Security & Construction
- Deadlocking Protection: The integrated auxiliary deadlatch plunger automatically engages when the door is closed, providing a mechanical block that stops the main bolt from being retracted from the outside.
- Fire-Rated Safety: UL/cUL Listed for up to 3-hour fire doors, this latchbolt ensures your facility remains compliant with rigorous building and life safety codes.
- Superior 630 Finish: The Satin Stainless Steel (630/US32D) finish provides the highest level of corrosion resistance and durability for high-traffic or high-moisture commercial environments.
- Grade 2 Performance: Built to meet ANSI/BHMA Grade 2 standards, ensuring reliable performance across hundreds of thousands of cycles in medium-to-high traffic areas.
- Seamless Retrofit: Designed as a direct factory replacement for the Accentra (Yale) 4600(LN) and 4600YC series cylindrical locks that utilize a locking function (Entry, Classroom, or Storeroom).
- Industrial Precision: Manufactured with a 1" x 2-1/4" square corner faceplate and a 1/2" throw for a robust, secure engagement with the strike.

Professional Maintenance and Compatibility
The Accentra MCD238 is a critical component for restoring the security of your existing Accentra/Yale 4600 series hardware. Each unit is supplied with a 1/8" sleeve (P/N 14-0378-9001) to ensure a precise, rattle-free fit in standard 1" door preparations.
For interior doors that do not require deadlocking security, such as passage or privacy sets, the plain latchbolt version—the MCP238—is the appropriate alternative. Both original factory parts are stocked in various architectural finishes at DoorwaysPlus.com.
