“M” jacks are available in several models which differ according to their use characteristics. They are provided with an automatic locking circuit and 10-metre flexible tubes.

The support is connected to two bearings which allow the jack to rotate on its axis, thus making inserting operations easy on the strands which protrude from the head.

The contained tensioning extension, the rotation of the jack on its axis and the support allow quick operations and limited efforts during handling.
