I was skeptical considering the Gladiator Gearboxes are almost double the price of these I figured that the quality would be poor but it is surprisingly similar to the Gladiator product.    Super simple to assemble.  Pro installation tip  I noticed some people complain that the doors weren’t square to the body.  Don’t tighten the screws of the frame all the way until you put the doors on and then it’s easy to square the frame and then tighten the screws.
