MCT Brattberg fill blocks, like the standard Insert Block, have always been sold as half blocks until now. That meant that some cables needed exactly twice as many half blocks to seal them where they were fed through a feed-through window. This sometimes resulted in uncertainty for some customers, because they assumed as many blocks as cables are needed. With the recent arrival of the HandiBlock, the flexible block that can feed 13 different cable diameters in one base block, the confusion was compounded as the HandiBlock was sold in pairs as standard: one pair of 2 half HandiBlocks for each cable. To avoid this confusion, MCT Brattberg will switch to a new minimum order unit from 1 March: two half blocks. This will apply to all MCT Brattberg feed-through blocks intended to seal cables: the standard Insert Blocks, HandiBlocks, U-Blocks, AddBlocks and all variants thereof, such as EMC shielding blocks or Atex certified blocks.
HandiBlocks
Recently MCT introduced Brattberg HandiBlocks. The HandiBlock is a flexible block, which is supplied in 4 different outer dimensions, with which different cable diameters can be sealed per block. In total, cables from 4 to 5mm can be sealed with only 4 blocks. The HandiBlock must be adjusted to the diameter of the cable that it is fed through. This can be done very easily by tearing off the InsertStrips and placing the correct size of the compression ring on both outer sides of the MainBlock.
