Product Overview

The MK.250-1 Winkhaus activPilot Concept locking bolt is used in tilt-and-turn window systems to provide secure locking of the sash. With a compatibility range that covers wood, aluminium, PVC, and steel frames, this locking component is well-suited for both modern and traditional fenestration applications. Its construction features a zinc alloy body with a galvanized coating for corrosion resistance, and it accommodates 16 mm hardware grooves. Classified for use in resistance class (RC) window assemblies, it meets security standards relevant in commercial and residential procurement.

The distinctive feature of the MK.250-1 is its use of an octagonal mushroom locking point, delivering enhanced protection against forced entry and improving the sash sealing. This specification minimizes project risk for window manufacturers and installers aiming to comply with RC security requirements, particularly in contracts for multi-family housing, office buildings, or public facilities demanding robust safety measures. The product is particularly suited for bulk procurement in window production OEM scenarios.
