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.
