🏠 Secure Every Patio & French Door

Why Patio Doors Need Extra Security

French doors, patio doors and conservatory doors are among the most common entry points for burglars in the UK.

Large glass panels give intruders a clear view of your home, and standard multipoint locks on double doors can be vulnerable to forced entry if the handles are levered apart.

Adding a dedicated patio door security lock creates a second line of defence — a physical barrier that prevents the doors from opening even if the main lock is compromised.

Anti-Snap Euro Cylinders for Patio Doors

If your French doors use a euro cylinder lock, upgrading to a TS007 3-Star anti snap cylinder is essential. Standard cylinders can be snapped in seconds. Our Avocet ABS and Yale Platinum cylinders provide the highest level of protection available. Browse our euro cylinder locks.

Sliding Patio Door Handles

If you have a sliding patio door, a worn or broken handle can compromise both security and ease of use. Browse our patio door handles for replacement options.

How to Secure Sliding Patio Doors

Sliding patio doors have different security needs to hinged French doors.

The most common weak points on sliding doors are the latch mechanism and the track. Intruders can sometimes lift a sliding door off its track or force the latch open.

To secure a sliding patio door, consider fitting a secondary track lock or a floor bolt that prevents the door from sliding open. A sash jammer fitted to the frame can also add a physical stop that blocks forced sliding.

For sliding door handles that are worn or damaged, replacing the handle restores both smooth operation and secure locking. Browse our sash jammers for an affordable secondary lock for sliding doors.
