Unless things have changed in recent years, these things cannot just be
swapped from brand to brand, model to model. The problem with
attaching them to the front of the track is the door itself will trip the
beam and reverse when closing. The only way I could imagine that
working would be if the sensors were mounted completely outside the
garage. That leaves them out in the weather, which they are not
designed for, and you are back to the issues with leaves and such.
If you live where it snows, that will be another problem. <br><br>
