Accentra MCP234 630 Plain Unguarded Latchbolt | 2-3/4" Backset | Satin Stainless Steel
The Accentra MCP234 Plain Latchbolt (formerly Yale) is a high-quality replacement spring latch designed for non-locking commercial door applications. Engineered specifically for the Accentra 4600LN Series cylindrical locks, this "unguarded" or plain latchbolt is the standard component for passage (F75) and privacy (F76) functions. Because it lacks the deadlocking plunger found on entry-style latches, it provides smooth, effortless operation for interior doors that do not require high-security shimming protection.
Fabricated with a durable 630 Satin Stainless Steel faceplate, the MCP234 is built to withstand the rigors of high-traffic environments while resisting corrosion and wear. Its 2-3/4" backset and square corner front make it a direct-fit solution for standard commercial door preparations in schools, office buildings, and healthcare facilities.
Reliable Interior Commercial Hardware
- Smooth Spring Operation: Designed for seamless latching on non-keyed doors, ensuring the lever or knob retracts and extends the bolt with minimal resistance.
- Passage & Privacy Optimized: The preferred "unguarded" latch for Accentra 4600 series hardware where ease of use is prioritized over deadlocking security.
- Fire-Rated Safety: UL/cUL Listed for use on fire doors rated up to 3 hours, maintaining the integrity of fire-rated partitions in commercial structures.
- Industrial Grade 2 Durability: Tested to meet ANSI/BHMA A156.2 standards, providing a long-lasting mechanical life even in demanding institutional settings.
- Premium Satin Stainless Finish: The 630 (US32D) finish offers a clean, architectural look that coordinates perfectly with other stainless steel or satin chrome door hardware.
- Universal 1" Prep Fit: Each unit is supplied with a 1/8" sleeve (P/N 14-0378-9001) to adapt the 7/8" latch diameter to a standard 1" door hole.

Professional Application & Maintenance
The Accentra MCP234 is a vital component for facility managers maintaining Accentra (Yale) Grade 2 locksets. If your passage doors are failing to stay latched or the internal springs have weakened over time, replacing the latchbolt is a cost-effective alternative to replacing the entire lockset.
For doors requiring higher security—such as entry or storeroom doors—you should utilize the MCD234 Deadlocking Latchbolt, which features a guarded plunger to prevent unauthorized manipulation. Both the plain and guarded versions are available in various finishes at DoorwaysPlus.com.
