Here's another What is this box called? >> 1900 box. >> Technically, yes, but no. You could say this is a 1900 box. This is actually, if you want to call it by the model number, it's a 232 Reiko. This is a 4 in square deep. This is like a 2 and 1/8 in deep. >> Oh, 232 Reiko. I remember that. So, a 1900 box. This is a 1900 box. A 1900 box is stamped out of a single sheet. This is a 232 Reiko. This is a 1900 box. This is about an inch and a half inch deep. Oh wow. The 1900 box, I feel like you can barely get any wires in that. How many wires maximum can go in that? Well, it'll tell you the cubic inch. You can always add an extension ring. It doesn't tell you how many wires you can put in here because you could put all different kinds of size wires, but it'll give you a cubic inch rating. It's stamped on there. You think you're going to exceed it. You could use an extension ring. And then it was this also has a cubic in rating. So the combination of both is how many conductors you can put in here. >> Wow, that's a lot of math. >> It is. Thanks, Ed. >> Oh, last one here. >> That is called a blank cover. >> Correct. This is called a blank. >> Blank. >> A blank. Blanks are very important. >> What's the difference between these? What are these called? >> Uh that is on your left hand is deep strut, right hand is shallow strut. >> That's right. >> What do you prefer? Uh, you know, I always prefer deep strut, uh, because it's easier to put in a spring nut inside of the deep strut, okay, >> over the shallow strut. But depends on what you're doing. Lightweight, you know, erector set kind of things, I would use the shallow. But structural, I'm definitely using the deep. >> Okay. Thanks, Ed. Yep.
