Adam Hall STRS6U Rack Stand 6U

For the most part this is every bit as good as could be expected.

I only have 2 qualms about this product.
One being the minor thing that only 12 screws are included, so in effect you can only mount 3 units without acquiring more screws elsewhere.
And then the major issue: The angle of the mountings is "less than optimum", so unless the bottom 2-3U are used for a extremely short unit, it won't fit! And I seriously doubt any unit is short enough to actually fit the bottom U.
So this should effectively be considered a 4U rack.

Beyond that it does what it's supposed to, and reckon it'll last plenty of years.
