Is this reef safe?

So I’ve been scrolling through Home Depot to find things to make a drag holder. Would something like this be reef safe? Says it’s plastic but used for ceiling lights. Just wanna make sure I’m not sticking anything in my tank that could damage or kill my reef. Also what could I use to cover it up and make it more “rock” like?

Same egg crate I use in my tank. Get black if it's available at your store it looks way better. The white stuff gets dirty quick.

safe. as mentioned above, get black. most vendors use this color to contrast the corals and make them pop a little more, and white tends to turn brown. black just gets covered in CA.

That's exactly what I used (and any others) to make a frag rack. Been in my tank for a couple months now and haven't noticed any issues.

Thanks everyone. I’ll see if they have black but either way I’m gonna cover it. Had a reef friend tell me to use black foam spray with sand and rubble to make a rock formation out of it. But if you guys have a better or easier way of doing it let me know.
