Question: I didn't see any reviews mention if this unit needs to be bolted to the floor to use. Does it?
Document: This rack is everything I expected it to be. Very sturdy and well made. Once bolted together, it does not wobble, shimmy, bend, twist, or sway. Its firm. It is a bit light so it may slide when you rack the weight if the weight is very heavy. But I don't have the rear of my unit properly in contact with the floor so that could be my fault.
Prior to buying, I thoroughly shopped around on Craigslist, online and locally. This unit had strong reviews and was the lowest price. This cage was very easy to assemble with three people. It's solid and it exceeds what we will need in terms of weight capacity. We highly recommend it!
Everything about this rack was great. When reading some of the reviews from other people, I was not expecting as nice of a rack as the one I received. The package arrived in good shape with no damage to the boxes at all. The paint is not chipping on anything except for one of the J hooks. We will have to see how long the paint holds up but it looks great as of right now. The welds look great and it was easy to put together by myself.
It also comes with rubber caps for the bottom of the base so that you do not scratch the floor. However, as noted in other reviews the paint on the pins and safety bars peels off very easily and can make a mess on your floor, but its not that big of a deal; I covered my pins in athletic tape and problem solved.
One thing though, don't tighten the bolts too tight, it can start to give a little and there is no need to do that.After a couple of weeks use, I don't experience that the paint peels off, so I think the manufacturer have listen to the earlier reviews and fixed that. The rack is much more sturdy than I anticipated and I feel very comfortable using it. I have dropped 240 lb.
Read the other more detailed reviews about this product. The featured reviews are pretty much spot on.-It's very sturdy-It does its job well-It does get minor paint scratching from use but who cares?
This is very commendable.As far as the construction goes, as I said, it is very sturdy. It fits my needs as an intermediate lifter perfectly. With the finish, the paint will flake off. This will happen to any rack with use but even upon opening there were some minor flakes and chips. This might bother my wife, it does not bother me so much as I will not be using it in an area where rust is a serious concern.
This rack is solid and it allows me to get the job done. No complaints at all. I don't see myself ever replacing it.
The rack is great. I have not put it under great stress yet but it seems okay. The only thing that I was unsure of is how thin the metal is. It was bending in when I went to tighten the bolts. We shall see.
Received my order within a week. While instructions say you need 3 people to put this together, I was able to do it myself, barefoot, in 45 minutes including unpacking. Unit is sturdy, the safety rods and j-hook pins are made of solid steel. Great product!
