What Sargent and Greenleaf does

Sargent and Greenleaf (S&G), founded in 1857 and headquartered in Nicholasville, Kentucky, manufactures high-security mechanical and electronic locks for safes, vaults, ATMs, gun safes, pedestrian doors, and perimeter padlocks. Its product portfolio spans electronic locks (A-Series OTC ATM locks, AxisBlu Bluetooth, NexusIP Wi-Fi, Titan, Spartan, Audit 2.0, Atlas), mechanical locks (8500, 6700, 6600, 6400, 6800 series, Model 2937, time locks), padlocks (Model 951/951C MIL-spec, Environmental Padlock 0881/0883, Model 8077), and federal-specification products including the 2890C (FF-L-2890C) and 2740B (FF-L-2740B) for SCIF and classified environments. S&G holds multiple GSA-approved federal and military specifications, UL Type 1 listings, EN 1300, VdS, CNPP, and A2P certifications, and operates a cloud-based management platform (SGCloud) and a keypad-free connected lock line (C-Series) launched in February 2026.

S&G generates revenue primarily through the sale of high-security locking hardware via a global distributor network including Anixter, IML Security Supply, Southern Lock & Supply, Lockmasters, and MBA USA, with direct sales to federal agencies for specification-compliant products and direct-to-consumer sales via Amazon for items such as the Atlas Model 1004 at $100 per unit. Reported revenue was approximately USD 45 million in fiscal year 2024 with strong EBIT margins, supported by roughly 100 employees at the Nicholasville manufacturing facility. The company serves banking and financial institutions, US federal government and military, healthcare and pharmaceutical, transportation and energy/utilities, commercial, and residential end markets.

Ownership transitioned in three stages: acquired by OpenGate Capital from Stanley Black & Decker in May 2019; Premier Steel Doors and the high-security locking division sold to ASSA ABLOY in 2024 and December 2025 respectively, with Delaney Hardware sold to Hillman Solutions in April 2026. S&G now operates as a wholly-owned subsidiary of ASSA ABLOY Group, continuing manufacturing operations at its Kentucky facility.
