The POWERTEX Master Link assembly MC4 is a Grade 10 master link assembly with two integrated connectors, each fitted with two shortening hooks, for four-leg chain sling assemblies. The integrated design allows all four sling legs to be adjusted quickly for different lifting applications while reducing the number of separate components compared with a traditional assembly.
Available for 6 mm up to 16 mm chain and from WLL 3t up to WLL 21,2t.
All models have a welded master link and forged connectors.
Also available as MC1 for one-leg assemblies and MC2 for two-legged assemblies.
