Concealed Vertical Rod Exit Device Overview

Concealed Vertical Rod Exit Devices (CVR) are specialized exit hardware designed for enhanced security and aesthetics in commercial doors. These devices feature hidden rods that extend vertically into the door frame when activated, securing the door at both the top and bottom. CVR panic devices are particularly useful in high-security environments or where aesthetics are a priority, as they provide robust exit functionality without visible hardware on the door surface.

CVR vs SVR Devices

Concealed Vertical Rod (CVR) and Surface Vertical Rod (SVR) exit devices are both types of vertical rod exit hardware, but they differ in their installation and appearance:

  • CVR devices have rods and latching mechanisms hidden within the door, providing a cleaner aesthetic and increased security.
  • SVR devices have visible rods mounted on the door’s surface, making them easier to inspect and maintain.
  • CVR devices are typically used on metal doors due to the need for internal channels, while SVR devices can be installed on various door types.
  • SVR devices may require more frequent adjustments, particularly to prevent bottom rod drag on the floor.
  • CVR devices offer better protection against tampering and vandalism due to their concealed components.
  • SVR devices are generally less expensive and easier to install than CVR devices.

Both types provide effective exit solutions, but the choice between CVR and SVR often depends on aesthetic preferences, security requirements, and the specific door application.

Concealed Rod Mechanism

Concealed vertical rod exit devices operate through a sophisticated mechanism hidden within the door. When the push bar is depressed, it activates a system of rods and latches:

  • The top rod retracts first, disengaging the latch from the header strike
  • The bottom rod then retracts, releasing the latch from the threshold strike
  • This two-step process ensures the door remains secure until fully unlatched
  • Upon door closure, a trigger mechanism resets the rods, re-engaging both latches

The concealed nature of the system provides enhanced security and tamper resistance compared to surface-mounted alternatives. CVR devices often incorporate a multi-step action in the top latch, which keeps both bolts retracted until the door closes, ensuring consistent relatching and improved door security.

Adjusting Concealed Rod Devices

Adjusting a concealed vertical rod exit device is crucial for proper functionality and security. The process typically involves fine-tuning the top and bottom rods to ensure correct latching and smooth operation:

  • Open the door and release the top latch bolt
  • Loosen the bottom locking screw and disconnect the bottom vertical rod
  • Adjust the top rod by rotating the top adjusting screw clockwise until the latch bolt is fully extended and deadlocked
  • Depress and release the pushbar to verify that the top latch bolt stays retracted when the device is activated
  • Reconnect and adjust the bottom rod, ensuring it doesn’t drag on the floor when the door closes
  • Test the device by opening and closing the door several times, readjusting if necessary

Proper adjustment prevents issues like scraping noises, floor damage, and inconsistent latching. Regular maintenance and adjustment of CVR devices are essential for optimal performance and longevity in high-traffic areas.

Heavy-Duty Panic Hardware

Heavy-duty panic hardware is designed for high-traffic and high-abuse environments, offering enhanced durability and security for exit devices. These robust systems typically feature:

  • Stainless steel components and heavy-duty construction for increased longevity
  • Heavy-duty relatching top and bottom bolts for improved security
  • Tested with the standard ANSI Grade 1  and UL testing requirements
  • End caps to deflect damage away from the device

These devices are particularly suitable for schools, hospitals, and other facilities requiring robust exit solutions that can withstand frequent use and potential abuse.
