Joist Hanger Size Question
 
I have a question if anyone can help me. My plans call for a "2x8 to 2x12" joist hanger SGL and "2x8 to 2x12" DBL.

I found the single hangers fine but I cannot find the double hangers anywhere. The question I have is can I just buy a 2x12 joist hanger or does the "2x8 to 2x12" mean something different? If anyone knows the answer, I'd appreciate any info. Thanks so much!

You can hang the one half of the double in the single hanger then slap the doubler on the outside of it and nail the doubler real good all the way down.
Or, if you're saying all you can find is a dbl 2x12 hanger, then that's fine.

Not sure where your looking but double hangers are pretty common. Any building supply Lowes and Home Depot all carry them.
No clue on all the other stuff your asking, there is no 2 X 8 X 2 X 12 hangers. It's one made for a 2 X 8 or a 2 X 12 not both.

They're 2x12 hangers, but they list them as "for 2x8 through 2x12 lumber".

Op: read my upper post again (I added to it).

The answer is that any lumberyard has them in stock or can get them...

Thanks
 
Thanks for the replies! It was confusing me because it listed the two different sizes. The guy at Lowes thought that a standard 2x12 would do it but he didn't seem confident so that's why I wanted to ask. Lowes and Home Depot simply list them as 2x8 or either 2x12 and I can only find a handful of websites that list them as 2x8 to 2x12. Some also listed them as 2x8-10-12.

I really appreciate you taking the time to answer my questions. I hope ya'll have a great weekend.

jj, you have to use a double hanger when the plans call one out. There is almost a 500# difference between the two, a single with a sistered joist is not per plans. Also, use the correct fasteners in the chart; http://www.strongtie.com/products/co...ace_ss-df1.asp

Show me something that says that, please.
Though there may be something about shear strength, thereby requiring a minimal amount of approved fasteners into the doubler at the end of the hanger esp.
Tinsel strength.
Like the hanger can handle 40,000 psi but nails only hold 39,500.
I guess I can see that.

But there's no 500# load difference.

And I know that you have to do exactly what the plan says. I didn't know if he's pulling a permit or not.
I was saying what is just as structurally sound.
And I don't know what the doubler is carrying. It could be sitting on a wall for all I know.

Go to the one I sited above:


2x10 group, LUS2x10--------under “FLOOR (100)”- 1340# with 10d nails, 16d not applicable--- notice fasteners in joist = 4-10d nails

DBL 2x10 group, LUS2x10-2----- under “FLOOR (100)”- 1830# with 16d nails, 10d not applicable--- again the joist fasteners = 6- 16d So the larger nail diameter and the shear angle nail number is more, together they help hold 490# more load in this example. Just saying, it would be a pain to remove a sistered joist just to replace a hanger that was called out by an Engineer who is taking the liability of the structure, not the framer or DIY homeowner.
