Had a few questions before I bought this rack. All were answered extremely quickly. Very impressed with the customer service. As for the rack itself, it is extremely well built and heavy duty. I've been using this kit for 3 weeks now and am very pleased with it. It was very easy to put together and when bolted to the floor is completely stable. Only small crticism is that it would be useful to have some kind of numbering system on the holes for the safeties and J hooks. Overall though this is a fantastic piece of kit and well worth the money.
