Yeah, and plus you don't just want a squat rack you want an adjustable rack so you can do everything in it....that would get very expensive to design an weld...but just buying a "squat rack" and not a "power rack" is a waste of money, imo.
Here is a unit that would work for you....
74 inches high. As you can see you have adjustable safefty catches. The only drawback is that the "pins" are not adjustable but are just hooks set at pre-determined height. However that can be worked with since there are plenty of levels....
Be careful about the width though. I was just looking at one from newyork barbells and realized the thing is only 46 inches wide This one I linked above is 64 inches.
Here's another one that would work well:
Edit* NM about the width. I got out my measuring tape and realized that mine is 47 inches wide (from upright edge to edge). I was thinking it was much wider but the width of mine is perfectly fine and 64 inches is actually way too wide, duh. I think the width on that bodysolid unit is a misprint.
