The Lug Style are made out of Stainless Steel, with the exception of sizes 1250-2000 MCM, which are made out of carbon steel. These Power-Grips™ are much shorter than earlier models, which is better for going around corners or sheaves. They have also eliminated one body size so that now just 4 different bodies are used to pull up to 8 different cable sizes from 1/0 cable right up to 2000 MCM cable.
