Thanks for the feedback and suggestions, everyone. I need to be fairly selective and choosy with this door's attributes. Many of the 'demo doors' I see (like the picture above) are mocked up to look like doors, but are really cabinets or non-standard assemblies. We need something that captures the major dimensional specs of a commercial door, not just a wood plank on hinges.
At the very minumum, I need an actual hollow core steel or solid wood door cutdown (standard 1.75" thickness), with an actual steel frame with standard throat and rabbet dimensions. I am planning to mount a mortise strike and some sort of lightweight maglock on the same door, so that it can be used as a 'universal' demostrator of those applications.
Even small details, like standard bevels and using actual door hinges are important so manufacturers don't fault a poor setup for issues. When it comes to hardware testing, an actual door will be needed, but for short demo videos of concepts and EAC system reviews, we need a fair representation.
Thanks to all who have volunteered to help!
