The Kawneer 1786 Rim Exit Device is a door hardware component designed for installation on doors. Installation instructions detail procedures for assembly, cylinder integration, and stabilization, with specific attention to component compatibility and potential warranty implications resulting from modification. The documentation focuses on the physical installation process and component identification.
Exit Device and Cylinder Installation
The installation process begins with the cylinder, which must be installed before the exit device itself. The documentation specifies a 15/16” cylinder with a 0.800” cam sweep for cylinder dogging applications. Utilizing cylinders longer than this specification may necessitate a trim ring to ensure proper projection. The cylinder is secured with a retaining ring and mounting guide plate, and a trim mounting base is also utilized. A lever handle is included, and is shown as a left-hand configuration in the provided diagrams.
The exit device installation involves sliding the pivot stile filler plate into the device, followed by attachment of the pivot stile end cap using provided fasteners. If the filler plate already includes a cylinder dogging mechanism, this step is pre-completed. Subsequently, the lock stile filler plate is slid into the exit device.
Dogging Mechanism Operation
The Kawneer 1786 Rim Exit Device incorporates a dogging mechanism that allows for securing or releasing the touch bar. To dog the exit device (lock the touch bar), a hex key is inserted and turned clockwise until it stops. The touch bar is then pushed. To undog the exit device (unlock the touch bar), the hex key is re-inserted and turned clockwise while fully depressing and releasing the touch bar.
Mullion Stabilizer Installation
Installation of the mullion stabilizer involves attaching frame portion stabilizers to the mullion using two #10-24 x 7/8" O.H.M.S. fasteners in the provided holes. Once the door is closed, the door portion of the stabilizer is aligned with the frame portion, allowing for a 1/16” clearance.
Removable Mullion Installation
For removable mullion installations, the shoe mullion mounting plate is first attached to the header/t-bar. The top shoe mullion is then attached to the mounting plate on the header/t-bar. Finally, the bottom shoe mullion is secured to the floor.

Important Considerations and Warranty Information
A prominent note within the installation instructions emphasizes that any modification to the exit device in the field will void the product warranty. Kawneer cannot guarantee the proper function of an exit device that has undergone any type of modification. This highlights the importance of adhering strictly to the provided installation procedures and utilizing only compatible components.
Conclusion
