GU
GU (short for Gretsch-Unitas) is a German, family-run window and door technology group best known in the trade for multipoint locking, door & window hardware, and automatic entrance systems. The company’s headquarters are in Ditzingen, Germany, and it positions itself around integrated “systems” for windows, doors and façades rather than single standalone products.
The GU Group manufactures and sells across several well-known brands, most notably:
-
GU – architectural hardware and systems for windows/doors/façades
-
BKS – locking technology (cylinders, locks, locking systems)
-
FERCO – hardware, especially prominent in the window/door fabrication world
In many markets (including the UK), GU is a staple name for uPVC/aluminium door locks and window hardware, plus higher-spec commercial solutions like escape route hardware and mechatronic locking, depending on the sub-brand and product line.
History-wise, multiple sources place GU’s origins in 1907 in the Stuttgart area, and the company has since grown into a global group with many production/sales companies across dozens of countries.
Our range includes premium GU components designed to support both emergency exit safety and advanced smart access control systems.
For emergency doors, we stock heavy-duty panic exit hardware compatible with the GU BKS Secury Panic E multipoint lock system. This includes robust push bar actuators suitable for heavy fire and escape doors up to 300kg, alongside matching 1150mm cross bars to ensure safe, reliable escape routes.
For modern access control, we supply the GU SECUREconnect 200 wireless power and data transmission system. This system allows secure, wireless transfer of power and data between the door frame and leaf, complete with dedicated faceplates designed for timber and uPVC doors.
Whether you are upgrading emergency exit doors or installing wireless access control, these components provide reliable, high-specification solutions for commercial and residential projects.
