    Patio Door Lock Security in Manchester

    Patio doors are one of the most vulnerable entry points in Manchester homes. Here's how to properly secure them.

    Patio doors — whether sliding, French, or bi-fold — are a beautiful feature of many Manchester homes. Unfortunately, they're also one of the most common entry points for burglars. The good news is that proper locks and security measures can make them just as secure as your front door.

    Sliding patio doors:

    Sliding doors are particularly vulnerable because:- Many have weak factory-fitted locks- They can be lifted off their tracks- The glass panels can be a weak point

    Security solutions:- Multi-point locking system- Anti-lift pins that prevent the door being lifted from the track- Patio door bar or track blocker as secondary security- Security film on glass panels- Key-operated locks instead of simple catches

    French doors:

    French doors present security challenges because they open outward and have a vulnerable slave door (the one that bolts into the frame).

    Security solutions:- Multipoint locking on the primary door- Shoot bolts top and bottom on the slave door- Security hinges (flag hinges are preferred)- Anti-jemmy strips between the doors- Hinge bolts on both doors

    Bi-fold doors:

    Modern bi-fold doors generally have good built-in security, but older models may need upgrading:- Multipoint locking systems- Anti-lift devices- Reinforced handles- Security shoot bolts
