Stainless Steel 90° Sliding Door and Window Lock

Secure sliding doors and windows with a compact, corrosion-resistant lock.

This Stainless Steel 90° Sliding Door Lock is designed to add a reliable extra layer of security to sliding doors and windows in homes, offices, and light commercial spaces. Constructed from solid stainless steel, it offers strong resistance to wear, tampering, and everyday use while maintaining a clean, modern appearance. The compact 44 x 19 mm body allows installation in tight spaces without obstructing door or window movement.

The 90-degree design is engineered specifically for sliding systems, where the lock components are mounted perpendicularly rather than in a traditional inline configuration. This ensures that once engaged, the sash is held firmly in place to help prevent forced opening from the outside. Suitable for wooden, metal, and aluminum alloy frames, the lock is ideal as an additional security point on balcony doors, patio doors, and sliding windows. Installation is straightforward using the included screws, allowing you to set up a secure fastening point on both the movable panel and the fixed frame or wall.
