What are anti-snap locks?

The inner cylinder is the most vulnerable aspect of a traditional lock as it can quite easily be snapped by intruders, without drilling or picking. If the cylinder sticks out more than 5mm on the outside, applying a small amount of pressure can snap it so it loses any protection it initially offered, making it easy to gain entry.

As leading double-glazing installers, we use modern and industry approved anti-snap locks which eliminate the common problems of snapped cylinder locks. It incorporates a precisely cut line in the body of the cylinder, so when force is applied, the mechanisms stay intact. For the homeowner, they function the exact same; by turning the key it pushes the spring-loaded pin out of the cylinder, opening the door. When locked, the strictly organized pins keep the cylinder in place so it can’t become loose.

What is a mortice lock?

Mortice locks are frequently added into both residential and commercial doors and use a simple key opening functionality. They secure the door on both the outside and inside, rather than within the material of the door. Mortice locking systems feature robust materials, innovative anti-pick features and solid hard plates to protect against drilling. These elements ensure they pass tests against common intruder techniques, giving homeowners confidence in their security.

What about additional door security features?

For property owners looking for even greater home protection, we can integrate a number of extra locking elements, including the following:

  • Night latches – these tend to be found on front doors and are fitted on the door interior. Providing a simple functionality, it doesn’t require a key to unlock the door from the inside of your home, making it a priceless addition in the case of a house fire. It adds security with its clever mechanism that automatically latches the door shut when the door is closed, bolting it to the door frame.
  • Door security chains – a door chain limits the capacity that a door can open. When the door is latched to the frame, it expands to a range that enables the homeowner on the inside to see who is outside but is small enough that a potential intruder couldn’t fit through or gain access.
  • Sash jammers – a popular supplementary security feature for both windows and doors, they stop the door from opening if the lock becomes defective through damage. Its design includes a small yet incredibly sturdy bar that overlaps the door panel when closed, so if someone attempts to open the door, the bar will continue to hold it closed in place. It’s easy opening system just requires the homeowner to press the lever down.
