Very happy with this purchase. I did not want to bolt anything to the floor so I I got the heavy duty X3. No issues, pull ups no shaking, attach the battle rope no movement. I added the multi grip pull up bar at the front so I bolted the thin pull up bar that was there to the bottom at the back. Added even more stability and is out of the way.
Great rack, deep enough to squat with the monolifts inside the rack. Very sturdy and the finish is good enough for our basement gym.
This rack is very well built, the quality of the holes and the fit together are excellent. The paint is also good. Note: the paint is a lot better than some of the landmine attachments I got mind 2017. The landmine attachment paint is rough and powdery, but the rack is smooth and A+. I did have an issue with one upright and Titan was easy to get a hold of and resolved my issue immediately. I'm in St. Louis and I typically receive my Titan gear next day or 2nd day!
Improvements would include better welds, I would rate the welds 7/10.
Next, would be mirrored j-cups vs 2 right side j-cups. J-cups fit nice no issues there.
Finally, the width is 42" (as of Oct 2017) I would like it to be 43" wide.
