The HandiBlock is a new safe, flexible and easy-toinstall insert block.
The sealing range is now fully adaptable to the cable/pipe diameter, within the module size. If a cable/pipe is scheduled or installed after the initial installation, safe installation can be achieved by using a reusable block. In this case, a main block, InsertStrip and HandiPlug can be assembled and installed as one unit at the point of initial installation.

When new cables/pipes are installed, the transit can be uncompressed and the module can be opened, adjusted to the cable/pipe size and reused as a cable/pipe holding module.
By retaining original parts in the transit frame, this process remains a certified solution.

Reality does
not always follow design

MCT Brattberg always puts safety first when developing new products. The HandiBlock is in line with this mission, but now provides the opportunity not only to put safety first, but also to keep safety first in the future.
This innovation offers a new safe, flexible and certified method for installing cables and pipes in the future.

Technical specifications

The HandiBlock is available in four sizes to fit cables and pipes or tubing from 4 to 54 mm. A HandiBlock consists of two compact half MainBlocks and two InsertStrips. Every compression ring on the InsertStrip has clear markings to indicate different cable/pipe diameters. This helps the installation technician to quickly and safely identify the correct size of the MainBlock, InsertStrip and compression ring.

The four block sizes can be converted into spare blocks when a plug is firmly anchored in the block. This spare module can later be opened and easily converted into a cable/pipe holding block.Compression and cable/pipe sealing is not achieved by deforming the HandiBlock parts. This means that all parts of the HandiBlock can be reused for repacking. Those parts of the InsertStrips, not used for the current block, can be retained and used for the cables/pipes where the insert dimensions correspond. This feature provides a cleaner and more efficient workplace, less wastage and assists in the clients’ efforts on environmental responsibility.

The four block sizes can be converted into spare blocks when a plug is firmly anchored in the block. This spare module can later be opened and easily converted into a cable/pipe holding block.

The MainBlock, InsertStrip and HandiPlug can also be purchased separately. This allows for cost savings and reduces wastage.HandiBlock can be combined with MCT Standard Insert Block, AddBlock and U-Block. Compression can be made by STG Packaging, PTG-Presswedges or RGP.

By installing a HandiPlug in the HandiBlock, you can quickly and easily create a spare block. This is a fully certified way to prepare for future cabeling/piping. HandiPlug’s low weight and smart design, together with HandiBlock, create a secure pressure-tight unit. The plug’s unique design also acts as a circular former for the sealing insert. Rather than being compressed and deformed into an oval shape, the plug enables the InsertStrip to retain its roundness even after an extended period of compression. The extensive testing carried out on the HandiPlug indicates that it can withstand harsh environmental conditions for over a century and can be reused over and over again. Each HandiBlock with a plug that is mounted into transit frames also provides extra fire protection. The part of the InsertStrip that protrudes from the MainBlock, acts as a small but effective heat shield.

Correct and safe installations

To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.
