The 431611 is an extruded aluminium (Sink Box Series) Heat Sink Enclosure. Ideally suited for mounting small printed circuit boards or chassis horizontally, the enclosure body is formed from a single, hollow aluminium extrusion. This gives the unit high strength as well as simplifying assembly. The aluminium extrusion has fins on one side (the top) which act as a heat sink, end panels are attached to each end.
Extrusions are anodized in black
Numerous slots on both of the shorter sides to accept a PC board or chassis
