4-11/16" Box

[Mr.Sparkle]

The only one that cares is you and other nosey electricians.

You have to die first for anyone to take notice of your art.

Well said.

Get off your high horse and use cowboys, nobody cares.

Sorry. :smile:

I have heard the terms "2100 box" and "11-B" to describe a 4-11/16 box. :roll:

Never heard of a "5S" until this thread ... :-?

11-B is a new one
I've heard 2100 for 4-11's and 2104 for 4-square boxes around here, but that's mostly the older guys (55+)

Why is unistrut 7/8" and 1-5/8" ?

to match the thickness of hatrack and the width of modern 2x4'S....

In both cases your 1/8" off.

We all know that the 1/8" makes up for the thickness of the can. When I first git in the trade we called it 1" and 1-1/2" unistrut.
Now most guys in the supply houses call it deep and shallow unistrut.
I worked with an older guy from PA that called it Kindorf.

They used to actually make 1" strut (not sure if they still do). Now it seems that 3/4" and 1.5" are the two most widely used standard sizes.

Maybe it had to do with manufacturing? Like, how many boxes could be laid out on a 4x8' sheet of steel.

That would be my guess too.
Minimizing material loss to scrap.

Back in the day when 4-11/16 boxes were first made, 2x4s were 2" x 4", not 1? x 3?"

They find a way to skimp on everything eventually don't they?

Maybe we should become a self-policing forum: Post something really terrible, then immediately delete it ourselves.

Remember when there was a much longer "Edit" time limit - if I remember right it was days.... So then you could not only edit hokey posts out yourself - but completely change points of an auguement....

7/8" and 1 5/8" - no idea where that comes from....

Yep. My 401(k) is now a 201(k). :grin:

Isn't Kindorf strut, from T&B, different in dimensions than Unistrut?

Hmmm not sure - but even the knock off stuff is the same size - well at least here.

Kindorf comes in 3/4", 1 1/2", 1 7/8", and 3" according to T & B.

Unistrut has more varying sizes from 13/16" to 3 1/4".
