Thin-wall coupling -- weak
Pros: - stainless steel - 1/2 x 13 size threaded rod coupling Cons: - walls of coupling are too thin for any application where great strength is needed. 5/8" open end wrench fits; 1/2"x13 Hillman stainless steel nuts use 3/4" wrench. See photo...

    These worked great for my outdoor project where I drilled and epoxied them into a cinder block walk! The threads are clean and I had no issues putting my eyebolt fasteners all the way through them without tools! I cleaned them first using IPA. My project turned out great and looks amazing! I bought these because I want my job to last! The top two wires are actually extension spring (so I don’t pull the wall over and they have lobster clasps on them so they can be removed for access). I hope this helps someone. Cheers

    Understand the thread needs for these couplers.
    While the couplers themselves are made well, the problem with these are that the swage cable fittings that I needed to connect are reverse thread and these are standard thread, so I wasn't able to use them at all for the decking project I was working on
