Add an additional garage door sensor
I have a Craftsman 1/2 horse model 139.53962SRT.
I've found it extremely useful having the sensor raised to match the car so the door will not close if the car is in the way.
But now with little ones running around I've put it back to it's proper location but would like to know if I can add another for the car, perhaps even by aliening a couple mirrors.
Any thoughts or remedies to protect the car without the string and ball trick and/or stoppers placed on the floor would be appreciated.
