Don-Jo CV-86 PC Mortise to Cylindrical Lock Conversion Filler Plate

The Don-Jo CV-86 PC Filler Plate is a specialized hardware component designed for the seamless transition from a mortise lockset to a standard cylindrical lock. This commercial door conversion plate allows you to fill the large 8" mortise pocket in the door edge, creating a new, reinforced mounting surface for a 2-1/4" cylindrical latch. It is the ultimate solution for mortise to cylindrical lock conversion, eliminating the need for expensive door replacement or messy wood fillers.

Whether you are upgrading an entire facility to a modern master key system or retrofitting a single office door, the CV-86 provides the structural foundation required for a secure, professional-grade installation.

Key Features & Performance

• Precision Hardware Adaptation: Converts an 8" mortise lock case cutout to a standard 2-1/4" x 1-1/8" cylindrical latch prep in seconds.
• Engineered Offset Alignment: Features a centerline that is 3/8" off-center of the plate, specifically designed to ensure the new cylindrical latch aligns perfectly with the strike in the frame.
• Structural Reinforcement: Fills the internal cavity of the door, providing a solid anchor point for the new latch and preventing the door edge from weakening over time.
• Architectural Prime Coat Finish: Supplied with a high-quality PC (Prime Coat) finish, allowing you to paint the plate to match the door edge for a clean, integrated look.
  
• Universal Commercial Fit: Measuring 8" x 1-1/4", this plate is compatible with the vast majority of standard commercial door mortise preps.
