I am doing a remodel that will result in a rather large walk-in closet.
Along one of the longer walls I would like to have a long closet pole
for hanging clothes. The thing is, I would prefer not to have any
braces or brackets during the run of the pole, just at the ends. This
is because I prefer to be able to slide all the clothes around a lot,
as it makes organization much easier.
I realize most closet poles are not strong enough to support that kind
of weight without brackets to the wall every few feet. I am looking
for approximately a 10' span with no brackets in the middle.
Has anyone encountered this situation and been able to come up with a
solution. I was thinking of a steel pole of some sort, which I imagine
I could find strong enough to support the weight. The other issue
would be the brackets on both ends, which would obviously be supporting
quite a lot of weight as well, so I was thinking not just bracing the
ends to the wall but to the floow as well.
You find a need to slide clothes more than a few inches or a foot?
I don't see how a single support in the middle would cause a major
problem. Aren't you going to have shelving above the closet rod? What
supports the shelving?
I built an 8' tall x 6' wide clothes rack with 2 rods with some of my
6-ton $500 collection of P5500 Unistrut from a dismantled warehouse.
It's a large erector set, mostly in 18' 45-pound lengths of 12 ga steel
in 2x3 U-shapes with one narrow open side and internal flanges to hold
special Unistrut nuts against the inside of the flanges with 1/2" bolts
and connectors outside. B-Line also makes Unistrut-standard stuff.
The clothes rods have the open side of the U facing up, and hangers sit
and slide nicely in the slots. The ends of the rods are attached to
the 8' columns (with the webs facing out) with 1/2" Unistrut nuts and bolts
and 90 degree Unistrut fittings. Each column is bolted to a 6' floor rod
parallel to the clothes rods and a 2' floor rod perpendicular to the 6' rod
(with all the floor rods open side up) with a straight shelf connector
that I bent to 90 degrees with an oxy-acetylene torch and 3 1/2" Unistrut
nuts and bolts. Tightened up with a long-handled 1/2" socket wrench, the
nuts and bolts are as strong as welds. The beam loading table in the 2002
Unistrut General Engineering Catalog (No. 14, North American Edition) says
the rods can hold up to 1090 pounds each, with a max deflection of 0.34
inches... 10' rods could hold 660 pounds with a 0.96 inch deflection.
If that's too much, you might enjoy the P5001 shape (like 2 2x4s stacked
on edge), with a 2260 pound load and 0.31 inch deflection for a 10' span.
Its columns could each support 6950 pounds, on a strong floor.
Yeah, the word "rod" confused me as well. I was just responding to
Bev's question about the deflection of P5001. I suppose he could hang
some individual sliding rods underneath it or something. Custom
I think this calculation is correct assuming all the weight is in the
middle. If the weight is distributed the full length of the rod the
deflectiomn would be a lot less. Even less if heavy items are placed toward
Another person, like Nick, who doesn't understand what he reads in a manual.
That's the problem with these manuals. They are useful for those who understand
them, but potentially dangerous in the hands of others.
Oh yes. The beam loading table on page 54 of the Unistrut General Engineering
Catalog (North American Edition, No. 14, 2002) lists 1.24". Furthermore,
deflection d = 5WL^3/(384EI), and the elements of section P5001 table lists
the 1-1 axis moment of inertia I = 5.578 in^4. E = 30x10^6 psi makes
d = 5x1130lbx240^3in^3/(384x30x10^6lb/in^2x5.578in^4) = 1.22".
Page 17 of the 2001 Cooper B-Line catalog lists a max 1593 pound uniform load
and 1.563" deflection for their equivalent B11A shape, which corresponds to
a 1130/1593x1.563 = 1.11" deflection with a 1130 pound load, with a note:
Based on simple beam condition using an allowable design stress of
25,000 p[si (172 MPa) in accordance with MFMA, with adequate lateral
bracing (see page 11 for further explanation.) Actual yield point of
cold rolled steel is 42,000 psi.
So I guess that you'd bend up your own hangers with that strut since
any typical hanger wouldn't come close to fitting.
Kind of makes your numerical exercise pointless, don't you think?
Nevermind, you've already answered that question.

But the P5500 will only support 260lb over 10 feet or 26 lb/ft. That
may not be enough to support clothes for some people.
I've know someone who converted an extra bedroom into a closet.
Four walls, none shorter than 10', covered with one (long clothes)
or two (shirts, jackets) hanger rods. Plus loads of shoe shelves
and drawers in the middle of the room.
My ex has a closet that is 12' long and full! That doesn't include
what's in the closets in the other rooms.
Something tells me that Nick isn't married to a typical woman. :-)
