Union
UNION is one of the big heritage names in British-designed locks and door hardware, with roots going back to 1840 in Willenhall (aka the Black Country’s lockmaking mothership). What started as a family business grew into a widely specified brand for everything that “goes on a door,” and UNION still leans hard into that made-for-the-trade, won’t-let-you-down identity.
Today, UNION sits inside ASSA ABLOY Opening Solutions UK & Ireland, and the brand acts like a hub for a wider family of door-hardware ranges. In recent years, brands like Exidor (panic/exit hardware), plus Dale Hardware and Excel Architectural Hardware, were brought into the broader “UNION family” after ASSA ABLOY acquisitions. It’s basically the Avengers, but instead of saving the universe they just make sure fire exits actually work at 3am.
What UNION is known for:
-
A huge spread of locks and cylinders (mortice locks, euro cylinders, padlocks, etc.)
-
The broader architectural hardware ecosystem: door controls, exit hardware, hinges, handles, accessories, and spec/support tooling aimed at installers and ironmongers
-
A strong UK trade presence and long distributor relationships (Aldridge even called out a 60-year partnership publicly).
Our range includes a comprehensive selection of UNION locks, latches, and accessories designed to suit both domestic and commercial security setups. Within this collection, you will find a wide variety of mortice locks, including 2-lever, 3-lever, and high-security 5-lever deadlocks and sashlocks, featuring British Standard insurance-rated options for external doors.
For rim-mounted installations, we stock a versatile selection of nightlatches - ranging from traditional non-deadlocking and auto-deadlocking models to rollerbolt and deadbolt configurations - alongside classic rim locks and drawback locks. We also supply Euro and oval profile cylinder lock cases, ideal for modern architectural door hardware integration.
To complete your installation, the range features essential bathroom locks, tubular latches, and a broad array of genuine UNION accessories, including rebate kits, strike plates, and forend plates to ensure a seamless fit.
