One of these special profiles can be used to produce a fixed-depth base or lid, whilst the remaining two can be used in conjunction with this shallow profile or entirely, to produce a much wider range of case dimension. The profiles are made into a case by means of special ABS corner ‘nodes’ that are pressed into the extrusions and a combination of adhesive and rivets, secure them in place, around the case panels.

The main difference with both the XT and the LX Range of cases, is that the rivets for securing the nodes and panels are on the inside of the case, not the outside as on traditional flight cases.  This means that the overall visual appearance is more aesthetic and therefore more popular with presentation cases and suchlike, as a very ‘clean line’ is gained from this method of assembly.
