I've read more of the other comments and think all are valid. Liability is something I've considered long and hard. Some of the design decisions reflect that. I'm not a big fan of working on any car that is being supported on soft ground. Personally, if I'm going completely under a car - I prefer a lift. Certainly this design could be made in a variety of heights and that is part of the plan. The initial jack stand was intended to cover a fairly broad spectrum of cars while limiting the number of initial molds that had to be created. This stand has a very large base. It will accept floor jacks with a wheel or handle widths as wide as 11.3 inches. So it will work with many Craftsman jacks, the nicer steel professional jacks, the often criticized, but frequently purchased HFT jacks, and a variety of generic floor jacks sold in auto parts or big box stores.
The cap is designed to lock over the top of the base (picture) and also designed so it won't slide off the jack plate of your floor jack. I must admit the initial target audience is somewhat specialized. As noted - it doesn't look cheap and while it is being produced in small numbers it won't be cheap. My thought is many guys have seen the damage you can do to a chassis, pinch weld, suspension mounting point, or floor pan of a car by jacking or supporting it in the wrong place. If you own an expensive car or one that has special meaning, you might want to spend the money to avoid messing it up. I learned about AC and Esco jack stands that are near $100 each and still leave you lying on your back looking for a place to put either the jack or the jack stand. This one won't make you do that. I'm using a pattern maker, foundry, machine shop, and finishers in northern Illinois. I would like to keep this an American made product. These guys have been great to work with and really supportive.
