X801-C Heavy-Duty Concealed Vertical Rod Exit Device - Top & Bottom Bolts for Maximum Security

Key Components & Features:

1. Concealed Design

• Unlike surface-mounted exit devices, this type is hidden within the door and frame, offering a more aesthetically pleasing look while maintaining security.

• The operating mechanism (rods, latches, and springs) is concealed inside the door.

2. Vertical Rod Mechanism

• Uses top and bottom rods (or sometimes just a top rod) that extend vertically to secure the door at both the head (top) and sill (bottom) of the frame.

• Ensures the door is securely latched at multiple points, improving resistance to forced entry.

3. Exit Device Functionality

• Allows for immediate egress by pressing a crossbar or touchpad, retracting the latch bolts for quick exit in emergencies.

• Often compliant with fire and life safety codes (ANSI/BHMA standards).

4. Applications

• Commonly used on outswinging doors in schools, hospitals, offices, and other commercial buildings.

• Ideal where security and aesthetics are important (e.g., glass storefronts, architectural doors).
