Crisscross NM head for aluminium joist

This new type of head allows to lay on the support one, two, three or four aluminium joists at the same time. It can be used as a replacement of the standard head for on or two joists or to support multiple joists on the same head; it is in fact a “cross joint”. 

The head is provided with 8 vertical preformed fins that hook the sides of the joists. The head is produced in two types: tilting for SE supports and non-tilting for NM supports..
