I ordered rm4100 rack, some accessories and 2 shanckles. I receice the 2 shanckles with different carabiner. All the othere products are excellent except for the different carabiner on shanckles.

Super solid and a large secure way to attach multiple attachments too as well as crossover symmetry set up. Prefer these over the artatchment post 100%. Their versatility and size triumph the post. Get the knurled knobs for each and still come in at a cheaper cost yet better product then attatchment post.

As with everything from rogue it is built like a tank M works flawlessly.

Strong ang sturdy for the cable pulley I hook up.

Some of my monster attachments don’t always have the signature monster powder coat. It’s a shiny one versus a matted one. I’m happy this one does. The steel is solid, the carabiner is top quality. I would definitely buy it again if I needed it.

I bought a pair to make attaching bands easier. They are built like a tank. The pair weighs in around 10lbs. Only thing I would change is to make the carabineer threaded instead of spring loaded.

I just setup my cable system using 3 of these shackles. Bought 2 separate cables, 8ft and a 13ft and closed the loop enough to string through my pulleys for ease of changeover. I use a loading pin for the weights and will need to build a landing platform later to protect the rack. The short cable for lat pull-down or other attachments using the upper heights. The longer cable use for low rows, legs, curls or whatever else i can find to attach. This was my only option as the rack lat machine would not fit my ceiling height not to mention the cost savings cant be overlooked.

We use this to do a lot of pull up work. My wife and kids like to hang straps on it for extra variety.
