3 Star Anti Snap Euro Cylinder

The national star rating system for lock cylinders goes up to three stars. To achieve a three-star rating, a cylinder must pass tests in three areas: drill resistance, snap resistance, and technical opening resistance. This lock passed all three tests at the highest level.

The technical opening time is 15 minutes or more. The national C-grade standard only requires 10 minutes. How did we achieve 15 minutes? We use a combination of 7 pins and specially shaped side blades. A normal B-grade cylinder has 5 pins. Lock-picking tools can open those in about 3 minutes. The 7-pin system and specially shaped side blades stop 90% of the picking tools on the market.

We placed three 6mm anti-drill steel pins inside the cylinder. When a drill bit hits these pins, they spin. The spinning absorbs the drill's energy, preventing the drill from penetrating the cylinder. We tested this ourselves. A normal cylinder took about 20 seconds to drill through. Our 3 star anti-snap euro cylinder withstood 3 minutes of continuous drilling, and the drill only made a small dent.

The anti-snap feature uses a reinforced steel plate. The plate is 3.5mm thick, which is thicker than our standard anti-snap cylinder. The anti-break strength is 15KN, which is 25% higher than our normal anti-snap cylinder. The axial pull resistance is 8,000N. That means if someone tries to pull the cylinder out with pliers, they will not succeed.

We sent this 3 star anti-snap euro cylinder to the National Lock Quality Supervision and Testing Center, where it passed all required tests. You can verify the report yourself. The cylinder fits euro lock bodies with a 72mm center distance. It comes with 3 keys as standard, and extra keys are available.

The warranty is 3 years. This lock is suitable for high-end homes, villas, government offices, bank branches, and jewelry stores. It features three anti-drill steel pins, a 3.5mm anti-snap plate, and a 7-pin system with specially shaped side blades. A thief is more likely to walk past this lock and try the next door instead.
