Overview
The EK 40SS-2 is a stainless steel #40 duplex connecting link (master link) designed to join two ends of #40SS-2 roller chain together. These links are manufactured from 304-grade stainless steel, making them ideal for corrosive and harsh operating environments. Each box contains 25 connecting links, providing adequate inventory for maintenance and chain repairs. The links comply with ANSI standards and deliver reliable chain continuity in industrial automation, food processing, and conveyor systems.
