We Make Your Life Easier

How We Serve You

Think of National Conduit Supply as your back office for all projects involving HDPE conduit, specialty conduit, innerduct, microduct, and more. We will have done the work for you, vetting all manufacturers to ensure that precise extrusion standards are adhered to, the highest quality resins are used, and that all materials have been inspected and approved for install. Best of all, you’ll be assigned a dedicated logistics manager that offers an immediate, single point-of-contact. The time and money our clients save in soft costs alone are substantial, and on national projects can relate to millions of dollars saved.

Meet Kathi Leiden, Founder of National Conduit Supply.

About Kathi:  She has built her career on consolidating supply chains for America’s biggest companies. The previous company founded by Kathi, Zephyr Solutions Inc. serves the biggest retailers in the United States, fulfilling their compressed gas needs, including helium, propane, nitrogen, and co2.

What she is most proud of:  “Beginning my previous company in 2008 on a shoestring budget, attracting a fabulous team of co-workers, growing the company exponentially, and ultimately selling majority ownership to a private equity firm in 2016 who will guide the company to its next stage of growth. It is the quintessential American Dream story.”

Humbled by:  “The fact that America’s largest retailers elected to renew long term contracts with us. It is a testament to the strong relationships we forged and the excellent, attentive, personal service we provide.”

Best compliment: “Someone once called me the ‘Matriarch of the independent supply chain.’ That comment was deeply meaningful to me. I love independently-owned businesses and the hardworking people that keep them going.”

Why she un-retired: “I am wired to work. I love solving puzzles, improving systems, figuring things out. Building improved, connected supply chains that support family-owned businesses and help leading companies execute on big projects is an exciting thing for me. It is not always perfect or easy, but it is what makes me jump out of bed in the morning. Running a successful business takes a lot of energy, creativity, tenacity and luck. Our NCS team has all that and more, and we are ready for the growing demand for conduit in building out the country’s communication infrastructure.”

What is National Conduit Supply’s business model:  “Truthfully, it is the exact same model as my previous company. Conduit is a fragmented market with only one, big national player. There are many distributors and manufacturers of conduit and accessories and our goal is to continue to consolidate and unite them under the NCS umbrella. By doing this, we have reliable coverage for every state. The customer gets the ease of process with one point-of-contact and centralized ordering and billing for their large regional or national projects.

The conduit manufacturers and distributors benefit because NCS can say ‘yes’ to national or large regional projects because of an expansive and diverse supply chain. When NCS gets a multi-year, multi-state contract with the government or with large telecom or electric companies, everybody wins.

It’s our ‘Win-Win-Win’ motto.”

Thoughts on the future:  “Everyone can see the tidal wave of 5G expanding into every corner of the USA. We are excited to be here to help with that national expansion. The fact that we are 100% female-owned and WBE- and WOSB-certified also makes us a great supply partner for companies committed to diversity spending.”
