Euro-profile lock cylinder — solid pure copper, multiple sizes, high security Key benefits Protects your home or workspace: multiple layers of resistance (anti-picking, anti-drilling, anti-snapping, anti-bumping) reduce common break-in methods so doors stay secure. Easy, fast upgrade: supplied accessories let you remove an old cylinder and install the new Euro-profile cylinder quickly without extra tools. Smooth, reliable everyday use: precision machining ensures the key turns smoothly every time, preventing jams and making locking/unlocking effortless. What makes it stand out Material: cylinder and key made from solid pure copper for durable performance and corrosion resistance. Security features: built-in anti-pick, anti-drill, anti-snap and anti-bump protections, plus fire-resistant construction for added safety. Options and compatibility: available in multiple lengths/sizes and offered in both double-cylinder and thumb-turn versions to meet different door and locking configurations. Designed as a direct replacement for standard Euro-profile cylinders. Function and performance Precise key action reduces wear and prevents sticking over repeated use. Robust core and hardened components resist physical attack methods commonly used on locks. Fire-resistant design helps maintain function and ingress/egress safety under increased temperatures. Quick installation Includes the necessary mounting accessories so you can replace an existing Euro-profile cylinder quickly and securely. Fits standard Euro-profile cutouts — choose the correct size (length) and model (double or thumb-turn) for your door. Practical applications Home front doors: upgrade to improved anti-snap and anti-bump protection for everyday family safety. Apartment and flat entrances: choose the correct length to match your multi-point or single-surface door lock and replace a worn cylinder in minutes. Offices and internal secure rooms: use thumb-turn versions for staff convenience or double-cylinder versions where key access is required from both sides. What to check before ordering Measure your existing cylinder length or door thickness to select the correct size. Choose double-cylinder if you need keyed access on both sides, or thumb-turn if you prefer one-side manual locking. Reliable, secure, and easy to install — a practical Euro-profile cylinder option for replacing or upgrading door locks without complicated installation.
