Overview

The NSI Industries EC-125 Mighty-Move® Expansion Coupling is a zinc-plated steel coupling engineered for 1-1/4" EMT (Electrical Metallic Tubing) in dry locations. This expansion coupling accommodates thermal expansion and contraction of conduit runs, preventing stress on connections and maintaining electrical integrity. Installation follows a simple process: slide the coupling end stop onto the fixed EMT, tighten the set screw, insert the movable EMT, mark engagement, remove and mark half the engagement distance, then reinstall to the half-distance position. The coupling measures 7 inches in length (Dimension A) with a trade size of 1-1/4". Designed for cost-effective, reliable performance in industrial and commercial electrical installations, the EC-125 provides a secure connection for EMT while minimizing labor costs and project timelines.
  • Zinc-plated steel construction for durability in dry locations
  • Accommodates thermal expansion/contraction of conduit runs
  • Simple set-screw installation with marked engagement points
  • Meets NEMA FB-1 and UL514B standards
  • Trade size: 1-1/4" EMT
