Innox INA SR4 Studio Rack (4U)

Like other sized units in this line, these are pretty well made, easy to assemble and feel fairly robust when assembled. Those reviews stating holes not lining up, or misaligned will almost certainly be due to user error during assembly. The instruction sheet clearly shows the side panels on the OUTSIDE. But we are creatures of habit and like to put lids on things. So if the top or bottom panel flanged edges are on the outside of side panels (which unfortunately is the instinctive way to put them together), then the holes will not quite line up no matter what you do. So follow the instruction sheet, simples!

I have noted some reviews saying they are not sturdy enough, I disagree, and suspect that's just lack of experience with 19" racks. Once you install your equipment and nip up the cage bolts, they becomes as solid as a rock.

Don't forget some racks are designed WITHOUT top or bottom framing or panels, just side pieces. In those cases they are designed to use the equipment itself, which once installed reinforces the rigidity. It's a natural feature of rack mounted equipment.

All in all can summed up with the following three points.
1. Reasonably well made (clearly machine formed so hole accuracy should be spot on every time).
2. Very easy and quick to assemble if you follow the assembly sheet properly.
3. Excellent value for money, can't argue with the price point.

I'll be buying more of these as my new studio develops.

This is a good value item and it does the job. For the reasons below I only gave it one star.
Whilst it was straight forward for me to put together I was surprised there were no instructions – it would have been easy to get things the wrong way round. One reviewer was critical and said the holes did not line up – I imagine it was because they were not doing it correctly – e.g. they could have been putting the side panels on the inside of the top and bottom panels rather than the outside. With the sides on the outside it all lined up perfectly.

The top and bottom panels have a lip round 3 sides – if it went round all 4 it would be much stiffer and enable things to be put on the top without sagging. At the moment it sags slightly at the back.
