Nemtek Compression 1 Hybrid (5kg 50 Units) Nylon-Black
These tensioners offer the following features:
* a combination of a compression spring to compress and expand as required and
* a mini titan to tension any slack that has been created over time
• a nylon plastic inner which eliminates galvanic reaction between dissimilar metal thus reducing rust and increasing the life of the wire
They are available in a standard tension (silver) spring which can tension 1.2 mm wires and a heavy tension (gold) spring which can tension up to 1.6 mm wires.
