About the company
C-Lock, Inc., based in Rapid City, South Dakota, manufactures livestock emissions-measurement equipment and precision agriculture monitoring systems sold exclusively to the U.S. Department of Agriculture's Agricultural Research Service as a prime contractor on a series of firm-fixed-price purchase orders with no small business set-aside designations.
C-Lock is a for-profit manufacturer operating 100% as a prime contractor across 52 federal purchase orders spanning 2022 to September 2026, with no subcontract work in the source record. The company specializes in GreenFeed gas-analyzing systems (which measure methane, carbon dioxide, oxygen, and hydrogen emissions from livestock), SmartFeed Pro automated feed-monitoring bins, pasture scales, respiration chambers, and associated data-access and maintenance-support contracts. Representative recent work includes a $691,057 definitive contract from USDA-ARS Midwest Area in June 2024 for three turn-key gas-flux measurement systems compatible with existing GreenFeed pasture units for delivery to Wyoming, Nebraska, and Wisconsin; a $468,690 annual subscription contract awarded August 2026 by USDA-ARS Midwest Area for data insight, remote monitoring, software support, and maintenance services across ten GreenFeed units at the U.S. Dairy Forage Research Center and USDA Marshfield Agricultural Research Station in Wisconsin; and a $358,801 purchase order from USDA-ARS Plains Area in January 2025 for two GreenFeed units and ten SmartFeed Pro units delivered to Oklahoma and Central Plains Agricultural Research Center in El Reno. Work is performed across multiple USDA-ARS facilities nationwide, with administrative oversight and manufacturing at the Rapid City headquarters.
Customer concentration is extreme: all 52 awards fund USDA-ARS regional offices or the central ARS organization. The Plains Area (35 awards, $2.3 million) dominates both volume and dollars, followed by the Midwest Area (8 awards, $1.7 million), central ARS (5 awards, $921 thousand), and Northeast Area (4 awards, $217 thousand). Combined potential value across the footprint stands at $5.1 million, with $4.7 million obligated (91% draw-down). Award velocity has remained flat at approximately five awards per year from 2022 through 2026. Within the next twenty-four months, four awards carrying combined potential value of $352 thousand reach completion and will face recompete exposure. The vendor competes under full-and-open procurement, with set-aside designations (Total Small Business) appearing on roughly 40% of recent awards but not serving as C-Lock's primary posture — most awards are unset-aside, suggesting the vendor wins on technical merit and sole-source continuation contracts rather than relying on socioeconomic set-asides. Primary NAICS codes reflect equipment manufacturing (All Other Miscellaneous General Purpose Machinery Manufacturing and Farm Machinery and Equipment Manufacturing account for 29 of 52 awards; Analytical Laboratory Instrument Manufacturing accounts for 11), while PSC codes track maintenance-and-repair services (14 awards) and specialized equipment procurement (20 awards combined across dairy/livestock, laboratory, and measurement instruments).
