Sacrificial Snap Lines on Asymmetric Euro Cylinders: Preserving the Cam Lock
Engineering Overview: Engineering analysis of sacrificial anti-snap lines positioned on the external lobe of asymmetric offset cylinders (30/40mm to 35/55mm).

Asymmetric Lock Snapping Defense
On asymmetric cylinders installed in thermal-break aluminum and thick rebated doors, the longer external section provides high tool leverage.
External Sacrificial Cut Placement
- Precise Location: Milled exclusively on the longer external segment (12 mm from the outer face), leaving the shorter internal side solid.
- Controlled Break: Snaps cleanly along the outer groove while the central steel bridge and cam mechanism remain deadlocked inside the mortise.
Frequently Asked Engineering & Selection Questions
Q1: Why are anti-snap cuts placed on the exterior side of asymmetric cylinders?
To ensure that when an attack occurs on the exposed outer door face, only the sacrificial outer tip breaks away, keeping the internal lock fully secured.
