RackSolutions2U 2Post Conversion Kit Server Rack Depth Extender

It's definitely sturdy enough, and works as advertised. But there is a problem, that isn't due to how this specific product is made. What you may encounter with a set of rails meant for a 4 post rack, is that they're thicker than other rails due to how their sliders are assembled(the synology rail kit is an example of this) and as a result can't fit in a 2 post rack with this conversion kit installed because the posts being in the center are in the way of the rails.Again, not a problem with this product itself, that's an issue of some rail manufacturers that may pose an issue if you intend to use this kit.

As described

Great product. Very sturdy.

I did not do my due diligence and measure before ordering this kit, so I cannot rightly rate it less than 5 stars. It is well built and the instructions are complete. The kit itself is easy to mount and is secure. I trust that it would easily support the weight of my three 1U servers.However, the R620 with the rapid rails was too wide. The R620 measures 17 1/8" and each rail 5/8". As in the detailed product description, the posts of my rack measure approximately 17 3/8" apart, allowing just enough room for the R620 and one rail, but not two rails. I am a bit disappointed.
