Open Sesame Model 133 automatic door opener for homes
The Open Sesame Model 133 automatic door opener is a low-voltage unit that powers a hinged house door both open and closed. It runs from a 24 V AC wall transformer, so no electrician is needed, and a 12 V battery keeps it working in a power cut. The door swings to as much as 120 degrees and stays open for 5 to 30 seconds. A clutch releases for normal use by hand.
