Mikolo Jammer Arms for Power Cage,2" x 2", 2" x 3" Power Rack, Adjustable Lever Arm Power Rack Attachment for Home Gym Attachments & Accessories, Fit for 1" Holes

Love these attachments on my Milokos smith machine. They’re easy to install and work well with my 2” plates

Arms are sturdy and move nice. But the pins slip off and the pin do not go all the way in on the back. Also the measurements listed are off slightly by about 0.1 to 0.4 inches on the arms. I would change my review if the seller could send me better pins for the arms.

arrived broken/missing pieces only one function arm....Update//first one arrived broken and missing connector.Seller hit got in contact and offered to replace / send me another set. So I will say costumer service will get a 5/5 from me. helpfully and offered to fix the issue right away.Now the review of the lever arms itselfBuild quality is fine. Fits on my 2x2 rack and will say it work as intended. where it lose some stars for me is first the safety pins that hole the grip is lose and have and will slip off. Not that safe. i plan to order / buy better fitting safety pins. On the other side of the grip, the weight peg will not hold the weight with the supplied weight claps. not safe at all considering. i use my own weight clip that i bought for my barbell to hold the weight. again please make sure you use better weight clips cuz the weigh will slide and fall off. So that's why the arm them self gets a 3/5 themself. They work as lever arms but with some major safety issues that can be resolve if you buy better safety pins and weight clips.

So I was used to exercises with similar attributes at the gym with cables to them and attached to weights that way. With this you're loading the weight on the arms yourself. One of the great things with this is that it does not need to be a movement on a path so you can do a variety of movements. It's also a detriment when you're first getting used to it. First time using it I loaded a 25 lbs plate and it was fine. Then I added a 45 lbs plate water that and the arms became unbalanced and started to (and did) slide off and nearly landed on my foot, and it did dent my rack. You might want to try out a few different techniques to safely load the arms. Once you've worked that out these are great.

These mikolo jammer arms are straight trash! If you are looking to get hurt these are for you. I have reached out to mikolo in the chat but they never connected. The weights fall off easily even clamped on. The pin can even come out easily. Should take these off the market asap!!!! I’ve purchased the folder rack and was good. I then upgraded to the Mikolo K3 rack which so far is good. The jammer arms is a waste of money. Want a refund, return, or credit. Outside the return window

Was using doing shoulder press after I greased the u joints and all and the left one u joint fell out. Keep in mind it was loaded with weight and I was hit with the plates and jammer arm. Don’t buy this

When loading weights always hold the arm and then let settle to safe balance - much horizontal free movement if not careful weights will fall on foot. That being the drawback to these arms the free movement has its benefits as you get a dumbbell affect when using these arms (e.g. on the bench press). Still have to figure out how to use these but feel as though it adds enough of a variation to be worth it. You just have to be careful and deliberate when using them.

Likes, Love the concept of these arms you can attach to your existing Power Cage Rack and do 15 or so additional exercises.Dislikes, one side the bracket that connects to the Power Cage Rack called a "Double U Seat Piece" is attached upside down and I did not want to beat it apart to try and correct it.Then the package comes with several ""Flipping Rings"" and Pinball pins for convenience and quick mode changes, however the pins do not stay in well and have some play in them.Lastly, the Spring Clamps are silly, order regular clamps if you're going to use these much.Overall I do like these Jammer Arms, I just think they could have been a bit better.
