Rack and Pinion Drive LKS 24 V S2

Good solutions are usually quite simple. Rack and pinion drives from AUMÜLLER help you save costs without having to compromise on performance and safety. LKS Systems are the cost effective alternative to electronic synchronisation controls and can synchronise two drives with no problem using a mechanical connecting shaft. It’s simple – and smart: an integrated electronic load cut-off protects the actuator from overload over the entire stroke length.

Roofers and facade builders need variable systems that are easy to install and do not compromise on safety and performance. LKS rack and pinion drives from AUMÜLLER offer a wide variety of mounting and casement brackets. They allow a wide range of applications with time-saving installation – preferably on outward opening light to mediam-heavy side-, bottom-, or top-hung windows as well as skylights. Thanks to their slim design and the wide rang of colour options, LKS systems can be integrated into any design.



  • through high-quality, durable, wear-free materials and inherently safe construction.
  • universally applicable, various mounting options, mechanically controlled tandem operation.
