GWG Gemeinnützige Wohnungsgesellschaft

"With around 19,000 residential units throughout Linz we offer modern and secure homes to 40,000 local residents", according to a statement on the GWG website. The over 32,000 mechanical EVVA 3KS cylinders which correspond to today's 3KSplus system underline the fact that it is not just an empty promise. GWG residents can also rely on first-grade security at front doors. The mechanical 3KS locking system is well-renowned throughout the world and provides maximum security thanks to drilling, scanning, picking and plug extraction. Thanks to the patented, springless functionality keys will last a lifetime – unlike in conventional cylinders where locking sliders are pushed against a spring, the locking sliders in these cylinders are moved using curve keys cuts.

This object was realised with the locking system 3KSplus, which corresponds to today's 4KS locking system.
