We are a small, family-owned business in St. Charles, IL. We take pride in providing fast, reliable service, with short lead times that allow us to ship most orders the same day when received by 2:00 PM Central Time. Less-than-truckload (LTL) orders are typically shipped either the same day or the next business day.

B&C entered the coupler business in 2003 and quickly became an industry innovator. We were the first company in the United States to design clear-center couplers, allowing installers to visually confirm that conduit is fully installed against the center stop. We were also the first to introduce color-coded couplers by size, eliminating confusion and ensuring the correct coupler is always used. For example, our 1 ¼” coupler features a clear body with blue ends for easy identification.

Today, we manufacture couplers ranging from 8.5 mm up to 2.375” (60 mm). All of our products are 100% made in the USA, fully dielectric to help protect against lightning strikes, and designed with a plastic gripper that increases strength and improves pull-out resistance.

In 2026, we expanded our product line to better serve the marketplace with two additional sizes: 27 mm with orange ends and 22 mm with pink ends.
