The MB Series from BCL Enclosures is a multipurpose ABS enclosure series with lids specifically designed to be flexible and customisable to suit multiple applications. All, except one model, have internal PCB slots (ribs) to retain printed circuit boards securely. 

The lids are securely held with M3.5 countersunk screws into brass inserts for a neat finish. This professional-looking series can be punched or drilled to suit individual applications.  

Eight different models are available in the MB Series:  MB1 measures 79mm x 61mm with a height of 40mm; MB2 measures 100mm x 76mm x 41mm; MB3 is 118mm x 98mm x 45mm.

MB4 measures 216mm x 130mm x 85mm, with a nominal wall thickness of 4.0mm; MB5 is 150mm x 100mm x 60mm with a nominal wall thickness of 2.5mm. All these models feature slots for retaining multiple PCBs. The dimension of MB6 is larger at 220mm x 150mm x 64mm, nominal wall thickness is 3mm, with no internal ribs.
