Product Details

Product Description

Our 72 series mortise locks are designed for high-frequency use and potential misuse applications, meeting the requirements of EN 12209 Grade 3. This CE marked euro profile mortise sash lock features 72mm centres and is designed as a reliable DIN style mortise lockcase for commercial and public building applications.

Manufactured from high-quality materials, the lock delivers dependable strength, stable operation, and long service life. It is suitable for timber and steel fire-rated doors, making it ideal for shopping centres, hospitals, schools, airports, and office buildings.

The lever handle operates the latchbolt, while the euro profile cylinder operates both the latchbolt and deadbolt. The reversible latchbolt allows easy handing for left-hand and right-hand doors, helping simplify installation and reduce inventory requirements.

The EN 12209 Classroom Mortise Lock is a euro profile cylinder mortise lockcase designed for classroom doors, school doors, office doors, meeting rooms, and other controlled-access commercial interiors. As a professional commercial mortise lock and architectural door hardware solution, it allows the lever handle to retract the latchbolt during normal use, while the outside lever can be disabled by key or cylinder control to restrict unauthorized entry. The inside lever remains active at all times for immediate, unrestricted egress, making this classroom function mortise lock ideal for doors requiring security, access control, and safe escape. With split follower operation, anti-thrust latch security, and suitability for fire-rated door and smoke compartmentation door applications when properly specified, this EN 12209 mortise lock offers reliable performance, safety, and flexibility for modern public building projects.
