Overview

The NSI Industries EC-125R is a 1-1/4" steel expansion coupling designed for use with IMC and Rigid conduit. This coupling is engineered to provide linear movement in long conduit runs, accommodating thermal expansion and contraction without stressing the conduit system. It features a true internal bonding jumper, eliminating the need for external jumpers and reducing installation complexity and part count. This design also protects the bonding jumper from environmental exposure, ensuring reliable grounding. Installation is simplified, requiring no disassembly and fewer tools, saving time and labor costs on the job. The EC-125R is a cost-effective solution for dry locations, offering a practical and efficient method for managing expansion in conduit installations. It is manufactured in the USA and distributed by Gross Automation. Key Features: - Size: 1-1/4" - Material: Steel - For use with IMC and Rigid Conduit - True internal bonding jumper eliminates external jumpers - Tamper-proof internal jumper protected from the environment - No disassembly required for installation - Faster, simpler installation with fewer steps - Exceeds code requirements for long conduit runs - Dry location application - Made in the USA
