Good rack not greatest shipping

Assembly: Takes a bit but overall rack was easier to assemble than I would have thought. Struggled with pull up bar but that was a lack of reading directions closely. Some washers missing but that may have been due to delivery/packing. Still able to get it done. Shipping: Came in 2 boxes. Box 1 was damaged in fact looked like maybe someone else had returned it and slightly opened washers, bolts, etc suggested the same. There was one noticeable ding in the back center but not enough to make me stop or return. Your patience level might be different but idea of not having a rack since I took my other one down already made me push through. Box 2 of 2 looked brand new and had no issues everything packed nicely and securely. Use: Still new but first thing I did and honestly feel like rack was begging me to do was try the pull up bar. It was the number 1 reason I almost didn’t purchase but it is nice. Neutral pegs feel great and as long as you work on edges pull ups handles aren’t to spread out. Rack it self feels solid no creaking. Solid construction without feeling overwhelming or taking up a ton of space. Suggest storing heavier plates up top and lighter ones down low. Improvements: Better shipping or packing. Another higher peg for fractional plate storage. Some more accessories. Finally pegs for bands would be solid. Thought a storage accessory for bands but couldn’t find it today. Worth the money but plan accordingly.

Great Rack

Low cost, but utilitarian rack that has a lot of options and stability, even without bolting to the floor. I would change the pull-up bar configuration, which wouldn’t add much to cost.

Highly recommend!

Anyone looking for a durable squat rack, definitely get this half rack. Easy to assemble, and perfect size for an at home gym!

No Attachment Options

It is sturdy and generally very solid. My big complaint is that unlike every other power cage on the market, this power rack is not modular at all. I have spent HOURS looking for dip attachments that might work and this rack must genuinely be the only power rack on the market that sells a 3x2 (width x depth) instead of 2x3 (width x depth). This means you cannot buy any attachments for use on this rack. Additionally, Grind does not sell any attachments for this rack. They won't even sell you additional J-cups! If you don't want PRx equipment (which is fantastic), just shop elsewhere. don't buy this half-rack, even for the price. I wish I had just paid an extra $500 for something that had more options.
