Interesting. What are you holding, there? I guess the shelf sits perpendicular to the door, but, last pic's angle makes it look like it's sitting on the latch.
'Tis at a 90º to the door, JUST off the floor, and the panic exit devices weigh about 20lbs± each.
The reason that they're there is because I need them on the truck, but don't want 'um on the floor, and they're too long for my shelves, in their boxes.
(I got needfully creative.)
WOW...They're, There, Their : ))))
As an aside ("P.S."), I opened this yesterday at a Getgo and I'm still walking on air. (These type of jobs are my biggest "ego strokers.")
