Hanging unistrut on vaulted ceiling

[vartz04]

I am thinking about revamping my garage again. The shelfs I have in there now (with homemade 2x4 shelf brackets) work but they are only 16" deep and the shelf brackets are always in the way of what I want to hang on the wall. My thought is to lag a 2x4 into the wall studs and then suspend the front using threaded rods/unistrut.

Will unistrut allow the threaded rods to hang plumb if installed on an angled ceiling? My garage has 8' high walls then there is a vaulted section that allows the center ceiling to be at 9'. My 2' deep shelf won't make it to the flat section in the middle.

I attached an image of the sketchup layout showing what I am talking about. I can't make the shelf deeper or it will be in the way of the garage door tracks.

IIRC, there is a Unistrut threaded rod attachment that is meant for that exact purpose. That said, I seem to recall that the max angle is about 15°. Chances are, your pitch is higher than that.

Let me see if I can dig up the part.

 

[vartz04]

roof pitch is 4/12 so that is the pitch of that portion of the wall. Using an online calculator that comes out to 18.4 degrees. Lets hope your part has a max of 20 degrees.

Unistrut and Cooper / B-Line have multiple options that are interchangable if needed.
If I remember though, the all threads can be expensive to where it may be more cost effective to get the 7/8 strut and cut to size to fit on your vaulted portion and then use some chain or more strut to make rigid.

Here it is. It's called a "swivel ceiling flange". The picture shows a 30° range of movement, but that's in both directions, so max of 15° in either direction.

Bummer.

Take a look at the Cooper / B-Line swivel hanger B446 or B446c. Looks like that could solve your problem.

Sammy Screws.

 

[vartz04]

Good call. Those Sammy screws are expensive though. I made need 10 of them

PM me your addy.

Option one
Make a bracket
Option two
Use chain instead of the threaded rod. Height adjustment can be made at the end of the eyebolt using double nuts

Personly....
I would advise against the project.
That is going to be a high shelf and at more that 16 inchs deep things will get pushed behind other things and be very hard to gt to

 

[vartz04]

All I will be putting up there is large light weight items (fert spreader with handles folded, roller seat, weed sprayers,) and a couple things that you rarely use during the year (leaf sweaper with back taken off for example)

everything I need on a regular basis goes under my bench on shelves or on the floor, in the cabinets above my bench, or in the toolbox. This will be the rarely used garage items. Unfortunately I can't build the shed I want so a lot of lawn/garden stuff spends its time in my garage and this is the best spot to put it.

I used this very stuff to hang my furnace in my garage and I have scissor trusses, it works awesome totally adjustable. And strong as heck.

I wanted to make mine a little less obvious and obtrusive. After I attached the main part of the shelf to the wall, making sure I hit the studs. I located the rafters and drilled and screwed in 3/8" hanger bolts, used coupling nuts to attach 3/8" all thread. Drilled a 7/16" hole all the way through the 2X6 and fastened everything in place. I don't plan on putting 1000s of pounds up there, but I tried my weight (200lbs) and it did not move.

I forgot to mention that someone had already put up some 1X4s over the sheetrock. I made sure I predrilled to get deep enough into the rafters. Here are some pics of work in progress. I have not cut the extra length of the all thread off at this point, I may want to hang something from them sometime.

Meh. My suspended shelf (built with superstrut) is 24" deep and runs from the front of the shop to the back of the shop. I put bins of heavy stuff up there all the time, not a big deal.

Perfect. I am going to do this or eye bolts and chain.

Thanks. The whole assembly is strong and easy enough to do by myself, with a couple of floor jacks and 2x4s'. I thought about all sorts of things, including chain, cable etc... and decided on the all thread for its strength and wont allow up or down movement if I bump it with something. I was going to cover it with some hose so you could not tell it was all thread, I have not done that yet.

This may be used to keep the area clear and free from needing upper support. These brackets can support upto 300# each depending on the length.
Here is a link to the Unistrut information and a link to Mcmaster-Carr for prices and sizes.

Here is what I used on my system. My wall brackets are approx 32" long and support a load of 250#. I have additional supports on the ceiling as well as two vertical posts to help spread the load, but are not needed for the weight the brackets are designed for. They are simply to add addtional support and to be used for mounting other items as you can see.

It puts the addy in a PM or else you get no Sammys from a friend.

Sorry, didn't see you were going a different direction.

 

[bob15]

T & B also make angle braces for mounting superstrut to walls.

Sent you a Pm plow

Fer real???? I sent you one to.

I'm not sure what you ended up going with here, but I found something that others might find some interest in. I found this post after looking for similar and decided to leave this in case others found this as well. It's a couple recommendations for sloped unistrut channel such as may be used in a vaulted ceiling.

unistrut is great and if installed properly can hold up a lot of weight. We use this stuff a lot to hold up some pretty heavy stuff like 4" conduit or even transformers. I will be building a rack above my garage door soon to store 4x8 sheets of plywood. I will be adding some 2x4 cross members in my attic to attach my all thread through and will be using 1/2" emt conduit over the all thread to dress it up and also as a spacer to separate it from the ceiling.
