Great read........but.......Would this be a good time to discuss violating the fire rating on the door and having to recertify it if an exit or corridor rating is required? This can be expensive to correct if not taken into account.

That's a good point... this tutorial addresses a non-rated frame/strike (most are), but in the case of a fire-rated opening, you rightly point out installing a non-UL/fire rated strike and (arbitrarily?) cutting the frame can create a big problem and safety issue.

I'll add a short disclaimer up front to your point. Thanks for the feedback!

How often are the wiring passages are covered with mortar in a block building?

Often, in my experience.  Drilling and chiseling mortar is a total pain.  Even when the frames have welded channels or boxes, there's always a place that is overrun with mortar.
