Winkhaus MK.500-1 Locking Bar 500mm activPilot Concept RC-Class Silver

Product Overview

The Winkhaus MK.500-1 locking bar from the activPilot Concept line is an extended-length espagnolette designed for tilt-and-turn (RU) windows in residential and commercial applications. With a total length of 500 mm, it is tailored for use in larger window sashes and is compatible with a variety of frame materials including wood, aluminum, PVC, and steel. The component features an octagonal mushroom locking point for secure closure, a 16 mm hardware groove, and a zinc die-cast body with corrosion-resistant galvanization.

Compared to standard locking bars, the standout feature of the MK.500-1 is its extended 500 mm length, which allows secure locking in oversized or tall window constructions without the need for additional adapters or multiple locking elements. This reduces installation complexity and ensures seamless integration in large custom window projects. The MK.500-1 is particularly suited for manufacturers and installers dealing with non-standard window sizes in premium residential or commercial buildings.
