“DD” jacks are available in several models which differ according to their use characteristics. They are equipped with 10 m long flexible tubes and spanners of different sizes for all the types of bars from 26.5 mm to 50 mm.

When a special spanner is inserted in the jack, the nut can be tightened. This avoids the use of seatings and manual tightening operations.

“DD” ” jacks have two robust handles for easy handling. The jacks operate with all the pumps at a working pressure of 550 bar.
