Not for these particular frames because they are hollow. Usually, all this is planned in advance and see what kind of door designs we are working with.
Haven't experienced On Call Service, if that's what you mean. We have a service department that take care of any service tickets and on call, from what I heard it sucks, because you can get called any second of the day, but there is benefits to it like going to take care of a ticket and fix it in 30 minutes and charge 4 hrs. Depends on how you see it.
That be cool, are installing any of the new systems that Walgreens has, like screens in front of the refrigerators? That shows all the items but on the door screen?
