What is the Difference Between Rim and CVR?

When it comes to panic exit devices, there are several options available, each with its own set of advantages and disadvantages. Two of the most common types are rim panic devices and concealed vertical rod (CVR) panic devices. In this article, we'll explore the differences between these two types and help you decide which is the best fit for your commercial door.

Rim Panic Devices

Rim panic devices, also known as rim exit devices, are one of the most popular options for commercial doors. They are mounted on the surface of the door and are designed to be used with rim cylinders. When the panic device is pushed, the latch retracts and the door can be opened.One of the advantages of rim panic devices is that they are easy to install and maintain. They don't require any special preparation of the door, and they can be quickly and easily installed using basic tools. They are also relatively inexpensive compared to other options, making them a popular choice for businesses on a budget.However, rim panic devices do have some disadvantages. Because they are mounted on the surface of the door, they are more vulnerable to damage and tampering. They may also not be suitable for doors with a lot of traffic or heavy use, as they can wear out more quickly than other types of panic devices.

Concealed Vertical Rod (CVR) Panic Devices

Concealed vertical rod (CVR) panic devices are a type of panic device that is installed inside the door. They are designed to be used with concealed vertical rod exit devices and are typically used on double doors.One of the advantages of CVR panic devices is that they are more secure than rim panic devices. Because they are installed inside the door, they are less vulnerable to tampering and damage. They are also suitable for doors with heavy traffic or frequent use, as they are more durable than rim panic devices.However, CVR panic devices do have some disadvantages. They are more difficult to install than rim panic devices and may require special preparation of the door. They are also more expensive than rim panic devices, which may make them less attractive for businesses on a tight budget.

Which is Right for You?

Deciding between rim and CVR panic devices depends on your specific needs and preferences. If you are looking for a cost-effective and easy-to-install option, rim panic devices may be the best choice for you. However, if security and durability are your top priorities, CVR panic devices may be the better option.It's important to consult with a professional when choosing a panic device for your commercial door. They can help you determine which type of device is best suited for your specific needs and ensure that it is installed correctly and safely.


In conclusion, both rim panic devices and concealed vertical rod (CVR) panic devices have their advantages and disadvantages. Rim panic devices are easy to install and maintain, but they may not be as secure as CVR panic devices. CVR panic devices are more secure and durable, but they can be more expensive and difficult to install.Ultimately, the decision between the two comes down to your specific needs and priorities. With the help of a professional, you can find the right panic device for your commercial door and ensure that it provides the security and safety you need.
