About Mainsheet, Inc.
Mainsheet, Inc., operating through its Huser Fire Fighting Equipment Division and doing business as Mainsheet Inc., is a self-certified small disadvantaged business based in Portland, Oregon, that provides FM-200 fire suppression system inspection and testing services to the U.S. Coast Guard as a prime contractor under small business set-asides and full-and-open competitions. All five recent federal awards—100% of Mainsheet's tracked federal footprint—are purchase orders from the Coast Guard for marine fire suppression system and fire extinguishers inspections, collectively valued at $16 thousand and delivered between December 2024 and May 2026.
Mainsheet's work centers on specialized FM-200 fire suppression system diagnostics aboard Coast Guard vessels. Concrete recent examples include a $3,017.50 total small business set-aside purchase order (May 20, 2026) for semiannual diagnostic inspection of three FM-200 systems aboard the USCGC David Duren, performed in Astoria, Oregon; a $3,045.00 full-and-open purchase order (January 22, 2026) for marine fire suppression system and fire extinguishers inspections in Ilwaco, Washington; and a $4,080.00 full-and-open purchase order (December 17, 2024) for fire suppression system inspections, also in Ilwaco. Inspections involve solenoid pilot valve removal and inspection, fire panel operation verification, pre-discharge delay testing, warning system activation confirmation, and CFR Title 49 Section 173.34 compliance verification, performed by certified Chemetron Fire Systems technical representatives. The company competes across both small business set-aside (three orders) and unrestricted (two orders) purchase order categories.
Customer concentration is absolute: the Department of Homeland Security U.S. Coast Guard accounts for all five recent awards and $16 thousand in combined potential value. Award frequency shows modest growth—one award in 2024, two in 2025, and two in 2026—with all work performed at domestic Pacific Northwest locations (Astoria and Ilwaco). Mainsheet operates exclusively as a prime contractor on these engagements with no tracked subcontract or subrecipient activity.
