This is my first experience with this manufacturer and I am happily surprised at the quality of the construction and well thought out design. They manufacture rackmount cabinets exclusively and it shows.
The most important features of the cabinet are the side doors. In addition to the door and removable rear panel, it is possible to remove the side doors therefore allowing good access to the sides of the cabinet for cable management and other installation jobs. Even though you can remove all the doors and panels they all lock for security purposes. You can see the cabinet with one of the side doors removed in the photograph to the left.
The second most important feature is the movable vertical rackmount rails. You can actually position them at any point along the depth of the cabinet and even add an additional pair of rails or several pairs of rear rails. Therefore with the additional rails you could accommodate deep and short equipment/sliding rails in the same cabinet without problems.
Personally I would have liked an additional pair of vertical rails to be included as standard. If you are ordering one of these cabinets then I would get them installed at the factory, you will probably need them in the future.
