Upotuslukko oikea 52.783S - 50 mm ruuviväli, 85 mm akseliväli, messingillä pinnoitettu etulevy

The 52.783S mortice lock stands apart through its right-handed orientation and precise 85 mm centre distance, a combination that simplifies installation on doors where the cylinder sits close to the lever. Its steel case and brass-plated forend deliver the rigidity needed for daily use without the weight or cost of a full multipoint system.

Highlights

• Right-handed mortice lock for wooden doors
• 50 mm backset with 85 mm spindle-to-cylinder centre distance
• Steel lock case with brass-plated steel forend (238 x 22 mm)
• Reversible latch bolt and single-throw deadbolt
• Accepts standard Euro profile cylinder (not included)
• 8 mm spindle follower for lever handles

In daily use

The lever handle operates the latch for quick passage, while the key turns the deadbolt for secure locking. Because the latch bolt is reversible, the lock can be adapted on site if the door swing changes. The forend's brass plating resists tarnishing and blends with classic hardware finishes. Note that the strike plate is sold separately, so order it alongside if the existing plate is worn or mismatched.
