SELEWARE Adjustable Lever Arms Jammer Arms for 2'' x 2'' and 3'' x 3''Power Racks, Heavy Duty Versatile Lever Arm Attachment for Gym Rows, Pushes, Deadlifts, Belt Squats, Curls and More

These arms are so versatile, and I am able to do so many exercises with them! ! They worked perfectly in my rack that is over 10 years old. (I bought the 3X3 inch arms.) I am very pleased and happier then I thought I would be by far! I highly recommend these jammer arms!!⭐️⭐️⭐️⭐️⭐️⭐️

Fitment was terrible. The 1inch adapter would not tighten on the peg. The mount did not fit flush with rack it tilted down with just the weight of the arms. The mounts would bounce against the rack flexing the welded areas on the mount when arms returned to the start position. The pin that holds the arms in place are weak. No way these mounts are rated at 300 pounds not even 150. The arms are great. The mounts or adapters are trash. It won't last

I bought these for a 3x3 (75x75) rack with 5/8 holes. These are my first set of jammer arms. I did not want to spend 3-4 times as much for a name brand product just to have them sit collecting dust. If I use them a lot I suspect I am going to need something built heavier.They fit snuggly on my rack with the included 3M rubber adhesive inserts. I intend to primarily use them on an up angle from my rack for a pull-up station (high enough that I don't have to bend my legs) and shoulder presses of various angles - static and dynamic.For pull ups one side sits about an inch lower than the other. Not a deal breaker as I simply turn around every other set to even out any asymmetry. The handles are a little on the short side for me (I'm 6'1") - so that I have what would be a wide grip if I was gripping a standard bar. I would prefer the handles to be longer so I could get a stander or even narrower grip.The description says it is rated for 600 lbs - I would never try to put this much weight on them. 300 lbs each side seems like a recipe for disaster. Even 100 lbs on each side for a standing dynamic overhead press the brackets were really flexing. I hope I never have to drop even that much weight. And if I jump up for the pull up station same thing - lots of flex when I grab the bar (I weigh 220 lbs).So far I am happy with them for the price, but well see how they hold up if I keep using them very much.

The media could not be loaded. Knowing limits and weight issues! I found this product to be a resource learning! There are many different ways to make it work! The majority of complaints is that needs lots of adjustments! Yes! It’s a mountable piece of equipment! Pain to keep adjusting but it’s a great tool! I’m still finding ways to improve the way for my body work outs! You just need to be creative and learn from people with experience on the gym tools! There are no limitations here! Good arms!

I use these arms on my Mikolo M4 All-in-One Smith Machine Functional Trainer and it feels dangerous. It doesn't have any guides to come back to the bars its attached to, so I have to be extremely mindful of my decline and not letting it go off the bar left or right which feels a bit of an oversight. Like many others, the bars feel cheap and I guess that's what you get for budget jammer arms but it feels cheap to the point of being dangerous. I rarely use these now as I have progressed past the point of weight this thing can or should handle (Like many others say, underload this thing, I wouldn't trust it with much weight) and find very little use for it now. A bit disheartening considering how much I paid. I would personally have just bought better quality arms but these do get the job done if you want to save a buck, but again, I would advise against that and maybe save up and get a brand name instead.

Attached easily to my cage and the ease and versatility is incredible. Just a change in hand placement allows you to pinpoint different muscle groups. Great machine addition.

I do like these jammer arms. However, customer serivce stinks. I've e-mailed both Fitvids and Signature Fitness both of which have not responded. Now I'm left with hardware that I don't know what to do with and not entirely sure if I've mounted the arms onto my rack correctly. No instructions or QR code for installation were included in the shipping box. The arms are sold by Fitvids but have the Signature Fitness brand on the arms and packaging. So I'm confused as to whether these are two separate companies or not. Now I will wait for a response...

SOMEWHAT SATISFIED...HOWEVER NOT A FAN OF THE SCREW PIN THAT HOLDS THE ARMS IN PLACEIT ALSO IS VERY TIME CONSUMING TO SWITCH POSITIONS OF THE ARMS
