Detmer Business Group Inc.

Detmer Business Group Inc., doing business as Summit Industries, is a small business subchapter S corporation based in Kettering, Ohio, that supplies specialized industrial and electronic components to the Department of Defense as a prime contractor on a 100% prime footprint, competing predominantly under Total Small Business set-asides on Indefinite Delivery Contracts with the Defense Logistics Agency.

The company's federal work centers on mechanical and electrical components for military vehicle, vessel, and aircraft maintenance and readiness operations. Representative work spans sensitive electronic switches (NSN 5930013248930 and related variants), fluid and filter elements, seal kits, magnetic contactors, electromagnetic relays, overvoltage absorbers, proximity switches, and related industrial parts. A $95,555.20 Total Small Business purchase order awarded in September 2025 by DLA Land and Maritime covered 40 units of sensitive switches with delivery to the San Joaquin Distribution Center. A $53,800.50 Total Small Business set-aside purchase order from March 2023 supplied electromagnetic relays to support DLA depot operations. A $40,402.08 Total Small Business award in March 2025 procured 16 units of sensitive switches with 168-day delivery requirements. The company also holds six active Indefinite Delivery Contracts with DLA Land and Maritime, each valued at $250,000 and designated as Total Small Business set-asides, covering seal kits (awarded February 2025), fluid filters (December 2024), fluid filter elements (December 2024), fuse plugs (May 2024), magnetic contactors (March 2023), and sensitive switches (January 2024). Work is performed primarily at the contractor's facilities in Centerville and Beavercreek Township, Ohio, with consolidation and containerization routed through designated DLA depots serving both Continental United States and international Defense Logistics Agency locations.

Customer concentration sits almost entirely with the Defense Logistics Agency: DLA Land and Maritime accounts for 313 awards (95% of the portfolio) with $5.5 million in combined potential value, followed by DLA Aviation with 48 awards ($175 thousand), DLA Troop Support Construction and Equipment with 17 awards ($68 thousand), and small exposure to the Department of Veterans Affairs ($30 thousand). The company has issued approximately 12 orders per year on its sensitive-switch IDC, nine orders annually on its fuse-plug IDC, and four orders per year on its filter-element IDCs, demonstrating consistent high-velocity procurement activity across component categories. Recent activity shows 33 awards in 2025 and seven awards issued in the first quarter of 2026, with two awards reaching ultimate completion within the next twenty-four months (combined potential value $13 thousand).

The company competes across three named parent IDCs within the Defense Logistics Agency: SPE7L425D61CV, SPE7M820D60UV, and SPE7M821D60QM. Approximately 30 percent of the company's recent contract portfolio carries Total Small Business set-aside designation, while the remainder compete on a non-set-aside, full-and-open basis. All work is firm fixed-price purchase orders and delivery orders; the company does not subcontract and carries no named teaming relationships in the source material.
