RDS 12L 

Our new 2-part connectable repair clamp made from high quality ductile iron.


The cleverly designed and simple overlapping feature allows an infinite number of clamps to be connected.


The repair clamps are available with galvanized bolts as well as with a combination of A2 bolts and CoNiSi nuts.


The decisive advantage of the A2 / CoNiSi material combination is that there is no risk of cold welding during the installation.
