Who's built one , and what hardware did you use?
Did the hardware work as well as you expected it to?
I have a gun room the client wants a hidden door that appears to be a bookshelves.
I've looked on line and Invisadoor hinge's at $150.00 seem pretty good, rated at 250 lbs. Halefe has some spendy hardware @ $1,600.00 + , but the description on line doesn't merit much consideration.
So who's done one or more , and what's the straight skinny on the hardware, and /or other pit falls?
TIA.
