This tray is heavy and robust. Slides smoothly. Attaches to back and front of a rack.
It did take me a while to figure out how to get the back braces through the rack mount because I'm using a 3U mount, so turning it diagonally didn't work. After a bit of head-scratching I realised that you can extend the braces fully and then you can push them narrower slightly to get them in. Then when through the back just slide the braces back into the body. DOH!
Hold my pedals nicely and slides out for access. Nice!
