Interior Cylinder Dogging Feature – Thumb Turn
The Cylinder Dogging – Thumb Turn function is available for our 3600 Series and 3700 Series exit devices, and eliminates the need for special hex keys to put the device into hold open mode. The Cylinder Dogging includes a standard thumb turn rim type key cylinder which can be changed in the field. Just a quarter turn by hand and the exit device is dogged open for unrestricted access. Cylinders and collars are available for both clear and bronze finishes.
