This rack was perfect for upgrading a network install which had been crammed into a cupboard far too shallow to take a decent sized cabinet. This rack wastes zero space and having the sides open means easy access; I was afraid it might be a bit wobbly given the lack of bracing but needn't have worried as this is a very sturdy (and very well finished) rack indeed.
No sharp edges anywhere; easy to assemble; decent sized holes for wall mounting; adjustable to the precise depth required - very impressed.
