These resin branch joints are suitable for all EPR, PE or XLPE insulated, PVC or LSF outer sheathed SWA cables as well as Lead (Pb) sheathed and PILC cables (additional earthing required). Variants also available for CNE, waveform or braided armour cables.

Each Birkett branch joint kit includes: two-part transparent mould, SWISHPAK resin pack/s, armour continuity braids, under-armour support rings, worm-drive clips, mastic tape and full installation instructions.
