NOTE
If the clock assembly does not line up with the junction box it is possible to increase the opening up to 0.3 inch (14.7
inches total) on either side as well as 0.2 inches (5.6 inches total) on the top or bottom. If these adjustments still do not
allow the clock assembly to be mounted to the junction box correctly, it is required to remount the junction box.
