This rack is awesome. It is exactly what I needed for my home gym. Some of the reviews about install, as long as you have a second set of hands, a stud finder and impact driver, you’re fine. Much like other people, my only wish is that Titan included mounting hardware and the option for their own stringer. I used 2x10s and bought 5x5/8 framing screws for the stringer to the studs and 4in lagbolts for the rack to the stringer. And this is solid… real solid. So solid I caused my impact driver to smoke. The hardware isn’t why I give it a 4 star. Buying all that on my own was cheaper, especially with free shipping compared to other brands. The drop in star is that it doesn’t really fold… once mounted there is no wiggle room to really move the arms in and out on our rubber flooring. The idea for this rack in my gym was to fold and save space… not a huge deal breaker in my specific case because I bought the 21in option so the footprint is still incredibly compact. All in all. Couldn’t be more pleased. The 3x3 X3 option is amazing. 3x3 steel is compatible with so many accessories for dips, landlines, spotter arms, single leg rows, belt rows… any that attaches to a full rack can go on this. Very happy with the purchase
