AV4 answers call for better locks

Thermal expansion remains a major challenge across the door industry, causing functional issues, increased service visits, driving up service costs, and frustration for installers and end users.

Recent Keystone market research into UK consumer fenestration trends revealed that 58.5% of respondents who identified security frustrations with their current doors, expressed a desire for better locks.

AutoLock AV4 from Winkhaus is designed to answer that call. With its ultra-low force-to-operate and wide installation tolerances, AV4 is engineered to stay dependable in all conditions, across all door materials and usage environments.

Independent testing shows that AV4 requires up to 70% less force to operate than alternative systems. According to Winkhaus, this makes it easier to use, reduces wear and tear, and extends product life, cutting down on service visits and complaints.

The system engages automatically with two anti-pushback hooks locking into place when the door closes, so users don’t need to lift handles or turn keys. It’s also PAS24 compliant and Secured by Design approved.

Winkhaus adds that for fabricators, AV4’s non-handed design reduces stockholding by up to 50% and simplifies ordering. Shared routing with other Winkhaus multi-point locks allows for easy interchange of functionality through fabrication and installation.

For installers, the system helps avoid costly call-backs thanks to its low-force operation, even when installed under pressure or exposed to shifting conditions over time.

In user testing, AV4 is said to have consistently outperformed competitor locks under simulated conditions that pushed doors beyond normal industry tolerance levels. Participants reportedly highlighted the ease of use, reliability, and long-term benefits.

Javaria, a landlord managing multiple properties, said: “Over time, doors become inherently more difficult to open. AV4 will reduce callouts and be easier to use for tenants in the future.”
Lee, a homeowner, commented: “Even as the door gets older and is open to the elements and wear and tear, it works – it was absolutely excellent.”
