Interlocks

At ML Markpluss, we provide high-quality interlocks that play a critical role in ensuring the performance, safety, and efficiency of our uPVC sliding windows and doors. Designed for tight sealing and smooth alignment, our interlocks enhance structural stability while improving insulation and security.

Made from durable uPVC or aluminum materials, our interlocks are engineered to join two sliding sashes or panels precisely—reducing air, water, and dust infiltration. They work silently behind the scenes, ensuring your sliding systems remain weather-tight, wind-resistant, and noise-insulated, even in challenging climate conditions.

The robust build of our interlocks ensures long-lasting performance and helps support multi-point locking systems, making them an essential component for homes and buildings that prioritize safety, energy efficiency, and smooth operation.

Whether you’re installing large patio doors, balcony sliders, or full-length sliding windows, ML Markpluss interlocks deliver superior fitting, better grip, and a cleaner aesthetic finish.

Count on ML Markpluss for reliable interlocking solutions that reinforce your windows and doors—quietly, efficiently, and effectively.
