    Spotter arms

    I bought a pair to go with my all in one trainer. The brackets on both arms were bent causing the arms to severely tilt forward and not hug the uprights properly. This would make the bar roll to the end of the arms. I contacted support. They were quick to respond and offered several options to remedy the issue. I eventually received replacement arms. The brackets were welded properly but the fit on the upright was still a little loose for my liking. I added some black velcro to the brackets to add some thickness. Now they fit tightly on the upright without issue

    Thoroughly Impressed!

    At Columbus East High School (Columbus, IN), we updated 12 of our racks with the Manticore Spotter Arms and we are very happy with the upgrade. The true 3"x3" dimensions fit perfectly with our existing uprights. They are extremely well made and sure to last for many years to come. Massive thank you to Andrew Ponsler for his assistance!

    Great!

    Fantastic and functional. I got the 2.3” ones to go with my residential rack. Budget oriented, but don’t let that make you think they won’t perform. These only skimp on “icing” things like liners on the bit the touch your rack uprights. They’re heavier duty than the rack itself.

    Only complaint, hence the 4-stars, is that the plastic liners are very soft. Much softer than the j-cup material, which I’m told is so it REALLY

    protects your barbell, but they are soft to the point that the are easily dented if you use them for other things (you can dig your fingernail into it pretty easily). Not a huge deal, but I’d way rather have the denser material on there.

    Overall, they’re awesome for the price and built-solid.
