A rim strike is a specific type of strike plate used in door hardware, primarily designed for rim exit devices. Unlike many other strikes that are mortised (cut) into the door frame, a rim strike is installed differently.
Based on the reference provided, a rim strike is defined by its installation method and purpose:
- It is the strike designed for a rim exit device.
- It is installed to the soffit of the strike jamb on the door frame.
- This installation method differs from most other latching hardware strikes, which are typically cut into the rabbet of the strike jamb.
- Its function is to be the component that the latch will engage as the door comes closed.
Key Characteristics of a Rim Strike
Here's a breakdown of the essential features mentioned:
- Application: Used with rim exit devices (also known as push bars or panic bars).
- Installation Location: Mounted on the flat face (soffit) of the door frame's strike jamb.
- Mounting Style: Surface-mounted, not cut into the frame like many standard strikes.
- Function: Provides a point for the exit device's latch bolt to secure the door when closed.
Example
The Von Duprin 299 Strike is cited as an example of a rim exit device strike.
In summary, a rim strike is a surface-mounted strike plate specifically for rim exit devices, installed on the soffit of the door frame to receive the latch bolt.
