Hey Guys, here’s a tricky one for yall.

I building two sets of bulkhead doors down to a basement.

Per design the doors are 8’+ long and 2′ wide. They haven’t been built yet, but I already know their going to be pretty heavy.

I’ve come across hydrolic assisted roof hatch hardware in the past and I’m woundering if anything like this exist for bulkhead doors.

Anyone out there know where I could find such a hinge?
