Next-level Security for your home

Easy to operate and install, multipoint locks can significantly increase your home security & protect against intruders. They can also turn an ordinary screen door into a true standards-compliant security screen door.

In today’s world, security is paramount, and it begins at the entry points to our homes, offices, and various other spaces. Traditional single-point locks have worked well for many years, but using a multipoint lock kit for your screen door does provide an additional layer of security and peace of mind.

Designed to enhance home security and provide long-lasting protection, multipoint locks create an impenetrable barrier that not only protects your home but also ensures your security door is compliant with AS5039-2008. Let’s take a closer look at multipoint lock kits and explore their benefits, operation, and why they are a superior choice when used with security screen-hinged doors and sliding doors.

Understanding Multipoint Locks

Multipoint lock kits (also referred to as 3-point locks or triple locks) are a sophisticated evolution of conventional single-point locks. Most people already know that a single-point lock is a type of screen door lock that has one central locking point in the middle of the door.

Multi-point locks differ from single-point locks in that they engage at multiple points along the door frame, making it more challenging for an intruder to force their way in. The key feature of multi-point locks is their ability to secure the top and bottom of the door simultaneously, along with the locking point in the centre of the door.

This is achieved by incorporating deadbolts and steel rods or cables into the door’s design, ensuring a comprehensive and robust security setup. The two most popular types of multi-point lock kits are cable-operated kits and rob-operated kits.

Compliance with security standard AS5039

Before we go into detail about how multipoint locks operate, it is important to understand their reference to Australian standards. AS5039-2008 refers to the Australian Standard for security screen doors and security window grilles. Homeowners with ScreenGuard security systems can rest assured – all ScreenGuard products are fitted with 3-point locks, making them compliant with AS5039-2008.

Operation of Multipoint Locking Systems

The operation of a multipoint locking system is both ingenious and user-friendly. When you activate the multipoint lock, the system engages auxiliary bolts at different points of the door. One of the remarkable aspects of these lock kits is their hidden nature. When the door is closed, the multipoint lock is concealed within the door frame, creating a sleek, discrete profile. The covert design of multipoint locking kits makes them an attractive choice for those who value both security and aesthetics.

Benefits of Multipoint Locks


  • Enhanced Security: The primary advantage of multipoint lock kits is their ability to provide superior security. With multiple locking points, it becomes extremely difficult for intruders to force their way in. The top and bottom locking points, in particular, add a layer of protection that is unmatched by single-point locks.
  • Compliance with Australian Standards: to ensure compliance to AS5039 security doors should be fitted with a 3-point lock. This not only deters potential intruders but increases the value of your home and may also reduce home insurance premiums.
  • Ease of Use: Despite their advanced security features, multipoint locking kits are remarkably user-friendly. Engaging and disengaging the locks is a simple process, making them accessible to people of all ages and abilities. They are also easy to install, with security fabricators frequently installing both cable-operated and rod-operating multi-point lock kits during the busy security season.
  • Retrofit: Homeowners with older screen doors need not worry, as most multi-point lock kits can be retrofitted – easily turning standard hinged or sliding security door locks into 3-point locks compliant with the Australian Standard.
  • Hidden Design: The concealed nature of multipoint locking systems adds to their appeal. When the door is closed, there are no visible signs of the locking mechanism, preserving the aesthetics of the space.
  • Durability: Multipoint locks are built to last. Their robust construction and materials ensure that they can withstand years of use without compromising on security.
