Industrial Sourcing and Procurement

Great Northern Products Great Northern Products is a NH-based Manufacturer’s (OEM) Sales & Marketing agency, and has been in business since first established in 1978.

Today we sell and procure Industrial, Engineered (specified) products through our online network Speksites.

  • Industrial OEM’s will continue to embrace online sales channels as they understand they are not about replacing established business distribution, but rather supporting and augmenting them by expanding their reach.

    • Our websites have brought us an entirely new set of OEM partners, and a far-reaching end-user customer-base. One consisting of forward-thinking companies on both ends.

    Speksites are owned and operated by Great Northern Products (GNP).
