Sliding door mortise lock for cylinder complete stainless steel (304) | GSV-Nr. 3801 SZ

The mortise sliding door lock with GSV No. 3801 SZ is a purpose-engineered locking solution developed specifically for use in sliding door systems. Unlike conventional swing or pivot door locks, this product addresses the distinct kinematic and structural requirements inherent to sliding door configurations, where force directions, door travel, and fitting geometry differ fundamentally from those of hinged door applications. Suitable installation environments include interior and exterior sliding doors in residential, commercial, and light industrial settings, wherever consistent, mechanically reliable locking performance is required over extended service periods.

The lock body and all load-bearing mechanical components are manufactured from stainless steel grade 304 or similar, an austenitic chromium-nickel alloy recognized for its robust resistance to corrosion, moisture, and common chemical exposure in both indoor and protected outdoor environments. Compared to standard steel or brass, grade 304 stainless steel delivers a significantly extended service life under varying climatic conditions without reliance on supplementary surface coatings that may degrade over time. The inherently smooth, low-maintenance surface of the stainless steel finish also satisfies the elevated hygiene requirements encountered in wet rooms, medical facilities, commercial kitchens, and food processing environments, broadening the practical application range of this lock considerably.

This lock is designed to accept a standard profile cylinder and is supplied without one, affording the installer complete freedom to select a compatible cylinder appropriate to the specific security level and keying requirements of the installation. The scope of delivery includes a coordinated strike plate, precision-matched to the latch geometry of the lock body to ensure clean, flush latch engagement without additional modification or site adjustment. The strike plate maintains the latch securely in the closed position and withstands the lateral loading characteristic of sliding door operation, providing consistent holding force throughout the product’s service life.

A technically significant design feature of this lock is the field-adjustable spring tension of the latch mechanism. Depending on the fitting type selected by the installer, the spring force can be configured to either a strong or light setting. A strong spring tension is recommended for heavier sliding door panels or systems requiring a more positive latch return, while a light spring setting improves ease of operation for lightweight doors or installations subject to accessibility requirements. This adjustability substantially increases the versatility of the lock across a wide range of door weights, sliding system types, and end-user needs, reducing the requirement for application-specific variants.

The lock is supplied without surface fittings, enabling the user to freely select handles, knobs, or lever sets compatible with the existing door hardware and interior design scheme. When using the optionally recommended handle models 2210, 6610, or 4410 in conjunction with this lock, vertical mounting orientation is mandatory to ensure correct mechanical engagement and sustained operational integrity of the complete assembly. This installation requirement is determined by the internal geometry of the lock mechanism and must be observed during planning and fitting to guarantee long-term, fault-free performance.
