Euro Cylinder Wallington

How a Euro Cylinder Is Measured – and Why Length Matters

For securing your home, getting the euro cylinder length just right is essential. We measure the cylinder from the central fixing screw to each face, noted as two numbers like 35/35 or 45/50 mm. This precision guarantees the cylinder sits flush with the handle, preventing vulnerabilities.

A cylinder that's too short will rattle, while one that's too long protrudes and becomes a target for lock-snapping attacks. Common fits in the Sutton area include 35/35 and 40/35 for 1930s-semi UPVC doors, and 45/50 for Hackbridge new-builds.

We always measure on site to avoid guessing. A perfectly flush anti-snap cylinder offers one of the most cost-effective and rapid security enhancements for modern doors.

If your cylinder protrudes more than a couple of millimeters past the handle, it's time for a swap. Call us at 020 3929 3672, and we'll guide you through measuring before we arrive.

Lock Snapping Explained – Why Anti-Snap Matters

Although it might seem like a simple security measure, understanding lock snapping is essential for protecting your home.

Lock snapping is a method where intruders snap the cylinder of a lock to access the door. This technique is alarmingly common on UPVC and composite doors in suburban South London.

We've seen how a standard euro cylinder can be compromised in under a minute using basic tools like pliers. This is why a TS007 3-Star Kitemark anti-snap cylinder is vital.

It's designed with sacrificial cut lines that allow the outer part to break away while safeguarding the core. This robust design prevents the lock from being picked or drilled.

Insurance companies are increasingly demanding these secure cylinders, especially on composite and UPVC doors.

We recommend this upgrade, particularly for Hackbridge new-builds and retrofitted 1930s-semis, ensuring your home remains secure against this common threat.

Replacing a Cylinder Without Replacing the Whole Lock

When considering door security, we often weigh our options between TS007 3-Star cylinders and 1-Star plus handle combinations.

Sometimes, a simple cylinder replacement can enhance security without needing a full lock change. We can upgrade to an anti-snap euro cylinder, improving resistance against common burglary techniques.

First, measure the existing cylinder. We'll need the correct size for a precise fit – measure from the center screw hole to each end.

Once we've the measurements, choosing a compatible euro cylinder is straightforward. Many opt for the TS007 3-Star rated cylinders, offering robust protection against snapping, bumping, and picking.

Replacing the cylinder is straightforward. Remove the fixing screw and gently slide out the old cylinder.

Insert the new one, ensuring it aligns perfectly. Secure it with the fixing screw, and you're done.

This upgrade is efficient and cost-effective, enhancing security without replacing the entire lock system.
