AUTOLOCK AV4 & THE DOOR INDUSTRY CHALLENGE
Thermal expansion remains a major challenge across the door industry: elevated and prolonged heatwaves mean door systems are under more stress than ever, causing misalignment, compromised performance, increased service visits, higher maintenance costs, and frustration both for installers and end users. With record high temperatures continuing, these conditions are not going away, and neither are the inefficiencies they create for fabricators and installers. The release of the latest Keystone Summer 2025 Consumer Trends Report shows homeowners are placing a growing emphasis on the performance and reliability of their door and window hardware. While aesthetics still matter, functionality, security, and ease of use are leading the decision- making process for many buyers. The Winkhaus autoLock AV4 is engineered for dependable performance in challenging conditions, across materials and usage environments. A Lock That Works When Others Do not. The autoLock AV4 delivers the reliability and install-friendliness both fabricators and installers need: Independent testing shows AV4 requires up to 70% less force to operate than many alternatives, significantly reducing wear and tear, making it easier to use, and extending product life. It locks automatically on door closure, engaging two anti-push-back hooks without needing to lift
a handle or turn a key.
PAS24 compliant and approved under the Police ‘Secured by Design’ initiative, delivering peace of mind for security as well as everyday practicality. With its wide tolerance hook-design, the AV4 is better able to cope with door movement from thermal expansion, settlement, or frame shift, meaning fewer adjustments and less wear-out risk. Built for Efficiency in Fabrication & Installation For fabricators and installers, AV4 simplifies life: The AV4 is non-handed, meaning one version fits left or right doors. This can reduce stockholding by up to 50% and simplify ordering and manufacturing. Share routing with other Winkhaus multi-point locks improves interchangeability and streamlines fabrication. Its robust performance under shifting door frames means fewer call-backs, fewer service visits, and more satisfied clients. Proven in the Field, Backed by End Users In independent user testing (field-simulation beyond standard industry tolerance levels), AV4 consistently out-performed competitor locks: users reported ease of operation, reliability, and long-term benefits. A landlord, Javaria, commented: “Over time, doors become inherently more difficult to open. AV4 will
