Specialty Fenestration Group

What Specialty Fenestration Group does

Specialty Fenestration Group (SFG) is a Houston, Texas-based, private-equity-backed manufacturer of specialty fenestration products serving government, commercial, quick-serve restaurant (QSR), healthcare, financial, entertainment, and education end markets. The company operates two principal sub-brands: Quikserv, which manufactures pass-through windows, transaction systems, ticket windows, transaction drawers, package receivers, and touchless automatic windows primarily for QSR and commercial customers; and U.S. Bullet Proofing (USBP), which produces high-security aluminum doors, storefronts, curtain walls, transaction windows, and wall armor engineered for ballistic, blast, forced-entry, and storm-impact protection. USBP holds approved-vendor status with the U.S. Department of State and supplies security fenestration to U.S. embassies and diplomatic facilities worldwide, while Quikserv supplies 45 of the top 50 global QSR brands and has shipped over 100,000 units globally, including installations at SoFi Stadium, Wrigley Field, State Farm Arena, and Kyle Field at Texas A&M. SFG's revenue model is built on project-based and specification-driven hardware sales through a combination of direct enterprise sales, channel partners, and a national distribution network, with go-to-market differentiated by end market — government/security customers buy through direct enterprise sales and regulatory approval, while QSR customers are reached via brand-level specification embedded in new-store construction cycles. The company is currently owned by Victor Capital Partners following a February 2026 acquisition from River Associates Investments, which had held SFG for eight years during which both sales and EBITDA more than quadrupled.

Broad incumbents
