For over five years I've had my Open Sesame door opener installed at my front door and with it getting used an average of sixteen times a day; I've never had a single problem with the opener. Professional grade Open Sesame door opener systems are assembled in the USA by our craftsmen. After assembly, your door opener is inspected and thoroughly tested, ensuring the high performance of all components. Open Sesame door openers are highly reliable, complete systems - and made in the U.S.A. We utilize the highest quality materials available: permanently lubricated steel gears, steel housing, and commercial-grade door release hardware.
