We are proud that the new AD/ADW -OB2000 Operating System used in our ADW-Standard System, ADW-C All Wood System, ADW-G All Glass System and ADW-T telescopic Door System has been designed, developed and is manufactured here in the USA using all American made components.

The software was written in-house at Sierra and the complete package is assembled and tested at our factory in Ontario, California.  We even burn the chips!

The development of this product represents a major step forward for the reliability of automatic sliding doors in the marketplace. 

End users from Alaska to Mexico, from Hawaii to Florida and beyond will attest that no other automatic sliding door in the market costs less to own.  Specify the Sierra ADW Series product with confidence.  Your customers, like ours, deserve the very best!

If your project is not "strictly low-bid," consider the ADW OB2000 system for your application.  No more embarrassing excuses for unreliable performance and expensive repairs.
