Double Open Euro Door Lock Cylinder Description
The double open euro door lock cylinder is ideal for anti-theft doors and front entrance doors. It features keyholes on both sides that require two keys to be inserted simultaneously to unlock (anti-misoperation design). It also enables independent locking from either the interior or exterior. This design significantly enhances two-way anti-theft protection: once locked from the inside, the outdoor key cannot force the door open; it features excellent outdoor anti-prying and anti-collision performance. Compliant with the European Grade C cylinder standard, the exterior incorporates mushroom-shaped pins and anti-pull steel balls to effectively defend against “lock bumping” and prying attacks. The internal structure uses multi-row pins combined with levers, connected to top and bottom door frames via vertical hooks to form a 3D locking system, increasing impact resistance by 30%.
Lomekin’s double open euro door lock cylinder complies with standard European profile dimensions, and its universal interface design enables convenient installation by directly replacing traditional cylinders or allowing upgrades without modifying the door body. It also adapts to synchronous locking structures for double-leaf doors, with cylinder lengths matching common door thicknesses (standard range: 70–90mm), and is compatible with over 90% of double-door and mainstream European anti-theft/fireproof doors.
As a direct lock cylinder manufacturer, Lomekin provides extensive customization capabilities to fulfill diverse customer requirements, covering cylinder materials, surface finishes, dimensional specifications, and tailored key configurations. Materials often include corrosion-resistant options (zinc alloy, aluminum, brass, or stainless steel), with premium surface treatments such as gold plating, zinc plating, chrome plating, nickel plating, etc. For length specifications, both standard symmetrical types (total lengths: 70mm, 80mm, 90mm, 100mm; split lengths: 35/35, 40/40, 45/45, 50/50) and asymmetrical types (total lengths: 85mm, 95mm, 110mm; split lengths: 30/55 or 55/30, 35/60 or 60/35, 40/70 or 70/40) can be produced. Additionally, personalized key systems of 3–5 keys per set (e.g., 2 regular + 1 emergency, 3 regular + 2 emergency) directly address common challenges like key shortages and the high costs of procuring additional keys, delivering practical and cost-effective solutions for end-users.
