Question: What are the small vertical bars at the back bottom of the rack? How does the rack assist with deadlifts? Can the rack be used for bench press?
Document: This problem only happens on the lower part of the upright. It goes through front and back upright just fine towards the top, but in the center, where I want the safety bars for benching, the spotter bar misses the back upright. It only does this on one side of the rack. the others sides uprights holes line up perfectly. Due to this problem I am not able to use the spotter bars when benching.
I hope they get back to me soon and help fix this major problem.Summary: the rack is a good price, is sturdy, but I can't use the rack alone since I can't use the safety spotter bars. This is a big deal as having spotter bars to allow me to work out alone was why I bought a power rack and not a squat stand. (Which is basically what I have now.)
One of the holes I use for the hooks on my bench press is a little off, and takes some effort to get the hook in place, but I imagine that will work itself out eventually.All in all I'm pleased with my purchase.
Safety bars are solid steel and heavy. Throw in a nice heavy duty bench and a mirror on the wall, and you've got everything you need for your own private pain factory.
It's wide and long enough to do Deadlifts inside if your limited in space a bonus for me. The paint job is very cheap and flakes easily but this is superficial if you take in account the price. In all if your thinking about buying a power rack and are in a budget this is a good power rack.
Great rack for the price! Got it for $319 with free shipping...you can hardly find these used at this price. On top of that, I orders it on a Monday evening, and it was at my house by Friday morning. Very easy to assemble. I assembled by myself in about an hour, maybe less. Very sturdy. Some minor paint flaws, but really doesn't matter. Hardware is high quality. This rack is legit!
This is a great rack, especially for the price. I use it for squats and bench pressing and haven't had any issues at all. To be fair, I'm not an olympic lifter or beefcake so it has only had about 300 lbs on it. I did have some worries about the quality but it is very sturdy and everything fits where it should with no trouble. Mine was missing the J Hooks when it shipped but I contacted their customer support and they shipped out a set that day.
Awesome Rack as good as a more expensive Power Rack, the safety bars are very heavy can withstand a heavy load. The Pull Up bar is awesome, i weight 230lbs and this rack did not budge a bit when i got on it, real sturdy, Read reviews that the safety bar wouldn't go thru all the holes but mines did fine.
The Rack: Exactly what I wanted and needed, with no frills or negative surprises. Feels sturdy and stable in use, doesn't rattle about or wobble if you drop a loaded barbell on the safety bars. Lots of functionality. Perfect for lifters who just want to get under some iron without the need to show off or surround themselves with fancy gear to convince themselves that they're doing something.Assembly: The rack went together pretty well, after we sorted out the nuts and bolts.
Very solid and very simple. No fancy stickers or gimmicks. Catch bars are nickel/chrome plated rather than painted like some. This makes them much nicer to handle without paint flaking and scratching off. J hooks are really heavy duty. I imagine the rack will fail long before the hooks do. Pull up bar is really sturdy as well. You can do elbow dips from one safety bar to the other or you can do full dips by placing two barbells across the safety bars placed higher.
Answer: yes
