French Door Security Guide for Manchester
French doors are elegant but can be a security weak point. Here's how to properly secure them in your Manchester home.
French doors add charm and light to Manchester homes, but they present specific security challenges. The double-opening design, glass panels, and slave door configuration all require careful attention.
French door security challenges:
1. Slave door vulnerability: The passive door (held by bolts top and bottom) is often the weakest point 2. Glass panels: Can be broken to reach internal locks 3. Outward opening: External hinges can be targeted 4. Meeting point: The gap between the two doors can be exploited
Securing French doors in Manchester:
Active door (the one you use):- Multipoint locking system with at least 3 locking points- Anti-snap euro cylinder- Quality lever handle
Slave door (the fixed one):- Shoot bolts top and bottom (key-operated, not just finger-operated)- Bolts should extend at least 20mm into the frame/floor- Additional mid-height bolt for extra strength
Between the doors:- Anti-jemmy strip (also called a rebate strip) prevents tools being inserted between the doors- Flush bolt set into the edge of the slave door
Hinges:- Flag hinges on outward-opening doors (the pin can't be knocked out)- Hinge bolts on the hinge side of each door- Security hinges with anti-lift pins
Glass security:- Toughened glass as minimum- Laminated glass for best security (holds together even when broken)- Security film as a retrofit option
