Advice on Correct Anchor to Use

I have what I think is a slightly unusual wall section (see attached). The layout is based on Curries products. Regarding anchors:

- I had considered using a multi-purpose anchor where one strap would wrap around the east side of the 2 x 6s, while the other strap would wrap around the sheathing on the west side. I have not been able to find any drawings of these anchors, but on-line sketches and photos seem to show that the center portion would interfere with face of the 2 x 6s.
- I then considered using a wood stud anchor, however, I am not sure if it can be ordered with a throat of 6-7/16" and spot-welded offset of center. I feel this is the ideal solution, but I am not sure it can be ordered this way.

Any comments or suggestions?

Thanks.

Yes, you do have a bit of an unusual wall there. But you have a few options regardless. There are several different anchor options shown on this page on our site which include explanations and drawings that you may find helpful. But we can handle that right here in the Forum...

First, the detail you included in the attachment shows the frame with double backbends...which are most common on KD (knockdown...not welded) frames that are installed after the drywall is up. These type of frames come with compression anchors already welded in them...which would serve your purpose. Here's a pic:

So a question arises - is the wall already up...and if it is, is the drywall up also? This will make a difference in the anchor options available to you. If the frame is a welded frame (usually has the standard single backbend) and is going to be set in place before the stud walls go up...running the studs up to the frame...then you have different options. There is also another scenario where the Curries frame your detail shows may be the Curries "CM" frame...which is a drywall type frame (double backbends) that is intended to be welded.

Regarding what you said here:
I then considered using a wood stud anchor, however, I am not sure if it can be ordered with a throat of 6-7/16" and spot-welded offset of center. I feel this is the ideal solution, but I am not sure it can be ordered this way.

Gulfport Industries sells adjustable 2 piece stud anchors (Part #FR380) that clip together by "hook & notch" at different throat sizes. These are used as snap-in anchors or are welded in...your choice. In your case, if you tack welded these in then you wouldn't have to use the hook & notch nor worry about throat size. Just tack weld 1 half of the anchor in place, then the other half right next to it wherever you need it.

Another choice would be welded in recessed Z-clips. You come in from behind the stud and screw into the Z-clip in the frame:

One more option would be to P&D (punch & dimple) the frame and then use 3/8" x 5" wood screws...or appropriate screws for whatever studs you have:

Thanks for your question!
