About C-Lock, Inc.
C-Lock, Inc., a Rapid City, South Dakota–based manufacturer of agricultural monitoring equipment, operates exclusively as a prime contractor (100% of recent awards) providing GreenFeed systems, SmartFeed Pro units, and related livestock emissions-measurement equipment to the Department of Agriculture's Agricultural Research Service. The company is a small business without SBA set-aside designation in its majority footprint, though roughly 40% of recent awards carry total small business set-aside designations under NAICS codes spanning analytical laboratory instrument manufacturing (334516), farm machinery and equipment manufacturing (333111), and miscellaneous general purpose machinery manufacturing (333999).
C-Lock's federal customer base is concentrated almost entirely within USDA-ARS regional offices. The Department of Agriculture accounts for 100% of the vendor's award portfolio, split across four distinct funding lines: the Plains Area office (34 awards, $2.2 million combined potential value) dominates the footprint, followed by the Midwest Area (7 awards, $1.2 million), the agency-wide Agricultural Research Service (3 awards, $676 thousand), and the Northeast Area (4 awards, $217 thousand). This customer concentration reflects C-Lock's single-agency positioning as the primary vendor for sophisticated livestock monitoring infrastructure across USDA-ARS research facilities nationwide.
C-Lock's capability portfolio centers on delivery and maintenance of turn-key gas-flux measurement systems used in cattle and dairy research. Representative prime work includes a $691.1 million definitive contract (June 2024, USDA-ARS Midwest Area) for three turn-key pasture systems measuring methane, carbon dioxide, oxygen, and hydrogen emissions from individual animals, with delivery to Wyoming, Nebraska, and Wisconsin; a $358.8 thousand purchase order (January 2025, Plains Area) for two GreenFeed units and ten SmartFeed Pro units to the Oklahoma and Central Plains Agricultural Research Center; and a $306.8 thousand total small business set-aside (September 2022, Agricultural Research Service) for three GreenFeed pasture systems with analyzers, feed dispensing, trailers, solar panels, and annual support to Marshfield, Wisconsin. Maintenance and data-access service contracts—ranging from $10 thousand to $57 thousand—form the recurring baseline: C-Lock provides hardware, software, and remote monitoring support for deployed units, plus unlimited access to raw and processed research data. Recent service work includes support for GreenFeed units, SmartScales, and respiratory gas chambers at facilities in Oklahoma, Montana, Wisconsin, and other states.
Activity has remained flat year over year across the five-year visible footprint (five awards annually in 2022–2025, with one award in the first quarter of 2026). The recompete cliff presents minimal immediate pressure: only four awards, with combined potential value of $245 thousand, reach ultimate completion within the next twenty-four months. Combined potential value across all 48 awards stands at $4.4 million, with $4.3 million obligated (98% execution rate). C-Lock operates no subcontractor relationships in the source data and places no task orders under government-wide IDIQs or GWACs; all work flows through direct purchase orders to the company's Rapid City headquarters and manufacturing operations.
