IHS Multi Strand Jacks


Product Description

IHS Multi Strand Jacks, also known as centre hole jacks or hollow jacks, are manufactured at our Port Melbourne facility. Stressing with IHS Multi Strand Jacks means that all of the strands in a cable bundle can be stressed simultaneously. The advantage of this method is the fast and accurate stressing operation of all the cables in one step.

Our multi-strand jacks come with a variety of options to suit your specific requirements. We have capacities of 110T to 1300T and strokes from 100mm to 300mm.
