I have an office building project using Mark Slot 2 linear LED. Curious if anyone has installed this or something similar (like Ray Neo) and if so, any tips for getting these set correctly?

My install will be in hard ceilings; there is no accessible space above the ceiling. I’m linking cut sheet and installation guide below.

It looks like I have to install the fixture on threaded rod prior to drywall. I’m thinking I will have to run string lines set to drywall depth to get these adjusted correctly. I can’t really tell if there is any adjustability once the fixture is in place.

Lucky you!

Hang them with threaded rod, string or laser to get them as close as you can to where you think the finished ceiling plane will be. Leave the nuts loose because it will be up to the rockers/carpenters to set the final position when they install the grid and rock.

I would have a meeting with the GC and whoever is doing the ceiling, framing, etc., and have them mark the location of ceiling height.
From the cut sheets it is hard to tell if adjustable, but appears to not be. And looking at the measurements, these are narrow, limited access from underneath once installed.
They appear to have two yoke styles, the one for rod is slotted , and looks like you attach the hanger to the rod and then fixture.
If whatever you will hang the rod from,(upper deck?) is not level, I would possibly hang the rod and put the hangers on and then cut the rod from the string line with a band saw. I think it would be faster than measuring from above, each location of a rod.
However it works out for you, I think this type of lighting will be time consuming to install.

Unless there is a grid to drop them into you have to use threaded rod and that's how you adjust them up and down. I also imagine that it's going to be a PITA to get them located in a straight line and where they should be horizontally. No way are you going to get the threaded rod perfectly positioned hanging from an anchor in the deck. So I'm thinking you may have to use a trapeze with strut, then hang the threaded rod off it with a T nut so you can slide it back and forth. This is a job for the carpenters, lathers or rockers to make the final adjustment. After you make the initial installation it then becomes part of installing the black iron, hat channel or grid and whoever does that.
