Euro profile cylinder in a mortise case (DIN)

The most standardised lock family on earth. A 17 mm × 33 mm profile cylinder sits in a mortise case built to DIN 18251, driven by an 8 mm square spindle, with a 72 mm centre distance on interior doors. If you design one adapter well, you cover most of continental Europe.

✓ verified · Where you will meet this lock: Germany, Austria, Switzerland, Netherlands, Nordics, Middle East, China (imported hardware)

Also called: Euro cylinder · DIN cylinder · Profilzylinder · PZ cylinder

⚡ 30-Second Retrofit Fit Check
3-Step Pre-Flight Verification to Prevent 90% of Stalls
1. Does Euro cylinder protrude ≥3mm from door escutcheon?
2. Does cylinder have dual-clutch emergency function (operable outside)?
3. Can multipoint handle lift smoothly to throw shootbolts?
✓ 100% Compatible with Euro Retrofit Locks (Nuki / Tedee / Linus)
⚙️ Operating Torque: 0.22 – 0.45 N·m (Standard Dual-Clutch)
Recommended: ADP-06 (Key Clamp) + ADP-09 (Assist Spring)

Anatomy

  • Profile cylinder — the replaceable keyed barrel, keyed both sides or with a thumb-turn inside
  • Mortise case — the box mortised into the door edge, holding the latch and deadbolt
  • Cam — the tab on the cylinder that throws the deadbolt
  • Follower — the 8 mm square hole the spindle passes through to retract the latch
  • Faceplate — the strip visible on the door edge
  • Strike plate — the pocket in the frame

Parameters to measure

Measure in this order: Centre distance, spindle-to-cylinder (Entfernung / PZ) → Backset (Dornmaß) → Cylinder total length and halves (e.g. 35/35) → Faceplate width × length → Spindle (follower) size → Door thickness

ParameterTypical valuesTolerance that still fitsHow to measure
Backset (Dornmaß)55 mm (interior), 60 mm; 65 / 70 / 80 mm on exterior and older doors±1 mm still fits most casesDoor edge to the centre of the cylinder hole.
Centre distance, spindle-to-cylinder (Entfernung / PZ)72 mm interior, 92 mm exterior; 78 / 85 mm on older doorsNone — this is the number that decides handle fitCentre of the spindle hole to centre of the cylinder hole.
Faceplate width × length20 × 235 mm or 24 × 235 mm; 24 × 280 mm on fire doors±2 mmWidth and length of the strip on the door edge.
Cylinder total length and halves (e.g. 35/35)30/10, 35/35, 40/40, 45/45 mm halves; total 60–90 mmMust be exact, in 5 mm stepsFrom the centre screw to each end, measured on the installed cylinder.
Spindle (follower) size8 mm square (7 mm exists on older hardware)NoneCalliper across the square.
Door thickness38–50 mm interior, 40–68 mm exterior—Measure at the lock, not at the corner.

Retrofit architectures that work

  • Motor on the thumb-turn — A geared motor clamps over the existing cylinder body on the inside of the door and turns the thumb-turn (or a key left in the cylinder). The lock case, cylinder, faceplate, keys and door prep are all untouched.
  • Electronics integrated in the cylinder — The cylinder itself is replaced by a cylinder with the motor, battery and radio inside. The outside keeps a mechanical keyway; the inside is a motorised knob. Nothing else on the door changes.
  • Motor replacing the interior handle — The interior lever or knob is replaced by a motor unit that drives the 8 mm spindle directly. The outside keeps the original key cylinder and handle. This is the cleanest fit for mortise locks where the bolt is thrown by the key and the handle only retracts the latch.

This is the best-served family for retrofit because the cylinder is a separate, standardised, replaceable part. Check two things first: does the cylinder have an emergency (double-clutch) function, and does the thumb-turn protrude enough to clamp.

Questions

Why does 72 mm matter so much?

Because the handle is drilled at that spacing. A 72 mm handle on a 92 mm case cannot be fitted without redrilling the door, which on a fire door is not allowed.

What does 30/10 mean on a cylinder?

The distance from the central fixing screw to each end: 30 mm outside, 10 mm inside. Order the two numbers separately, never just the total.

What is an emergency function cylinder?

A double-clutch cylinder that can still be opened from outside with a key even when a key is inserted inside. Every retrofit motor that leaves a key in the cylinder needs one.
