Five of these individuals photographed in 1910 (pictured above) went on to build Kuker-Ranken, opening in 1924 and officially incorporated in 1928, providing Architectural, Engineering, Construction, Survey Equipment and Supplies to the precision industry ever since.

Kuker-Ranken was founded in 1928 by W.J. Ranken, Otto J. Kuker, Jack T. Ranken and Harry G. Kimball as a manufacturer of the Kuker-Ranken hand levels for contractors and surveyors. Initially located in Renton, Washington, Kuker-Ranken, Inc. has been in a number of locations over the years. From Renton we moved to 4th & Columbia downtown Seattle, WA it was current location of McCormack’s Fish House, where we expanded into architectural and engineering supplies including blueprinting tools, eventually moving to 818 John St in Seattle.

In 1978 we became the area dealer for a Swiss company called Wild Heerbrugg a manufacture of the highest quality survey instruments to our product line, currently known as Leica Geosystems, and in 2021, we focused more deeply on robotic systems as we opened our UAV drone division.

We moved to our current Mountlake Terrace location in 1980 and added our Fife store in January 2002 and our Beaverton, Oregon store in January 2003. In 2016 we added Salt Lake City and Las Vegas to the list of KR locations.

Kuker-Ranken was purchased from the founder’s family in 1977 by Gary and Sandi Rousseau. Gary and Sandi successfully ran the business for 28 years and is now owned by Robert H. Lycke Jr, a longtime employee of KR who worked his way from being a shipping room clerk to owning the company.
