Open windows and doors, but locked

There are many advantages to having open windows and doors, but leaving them open isn’t always an option. With the LockLatch you can get these benefits without having to deal with the worry of an unsecured home or work place. Open windows allow for better ventilation and airflow as well as providing easy access for your pets.

Prevent Office Theft

LockLatch is also a great way to secure your home office. These spaces usually contain expensive electronics and sensitive documents and so extra care needs to be taken to ensure the security of your remote office. LockLatch can be easily fitted onto your office window to allow fresh air to circulate, leading to improved concentration and comfort while you work.

Upper Floor Restrictor

LockLatch and MiniLatch also make fantastic window safety restrictors. This is useful for the parents of young children, who are mobile enough to climb out of windows, but too young to understand the risk. The device lets you leave upper floor windows open, but to adjust the gap to be too small for children to fit through, so you can enjoy the fresh air without worry.

C304 Stainless Steel

Part of what makes the LockLatch range of security devices so durable is the C304 stainless steel used in their construction. This material is tough and able to withstand even the toughest conditions and also keep opportunistic thieves out. It is also highly resistant to corrosion and won’t be damaged by prolonged exposure to the elements.

Adjustable to fit all windows and doors 

What really makes LockLatch stand out is its versatility and this is largely due to the unique design and adjustable stainless steel arm. This not only means that you can adjust the size of the opening to suit your needs, but also allows the device to be installed onto any type of window or door regardless of the style or material.

Home ventilation  

The benefits of fresh air flowing through your home cannot be overstated. Fresh air has a wide variety of health benefits from simply helping you sleep more soundly to improving concentration and cognitive functioning. Improved home ventilation also helps reduce the amount of allergens such as pollen or dust in your home, as well as preventing the formation of mold colonies.

Prevent home burglary

All three devices in the LockLatch range are intended first and foremost as security devices to improve home security. They are a great way to add that extra layer of security to your home to discourage opportunistic thieves looking for an easy score. The revolutionary design also means that they are a completely universal solution able to fit any type of door or window.

Dog and cat door alternative 

LockLatch and PetLatch provide a fantastic alternative to traditional dog doors and cat flaps. PetLatch is designed predominantly for small to medium-sized dogs and doesn’t require you to cut a hole in the door for installation. It has the added advantage of being adjustable so you can change the size of the opening as your pet grows. LockLatch can also be used to provide access for your cat through their favourite window meaning they can come and go as they please.

Protect against wind damage

Even a gentle breeze can cause certain types of doors to slam if they aren’t properly secured. This can lead to damage to the door or frame or even cause hinge failure. The same can be said for windows where a slam can lead to broken window panes. LockLatch prevents this from happening by securing your door or window in place.

Secure caravans motorhomes and boats 

Caravans, motorhomes and boats both suffer from similar issues when it comes to window and door security. They are often made out of difficult to work with materials and feature unique types of doors and windows as well as hatches. At the same time these openings are essential sources of ventilation. LockLatch lets you leave these open to allow the fresh air to flow in, without worrying about break ins.

Stop pests from entering your home 

Raccoons and possums may look adorable, but anyone who has had them in the home, knows the mess these critters can cause. Luckily you can use a LockLatch or MiniLatch to leave your windows open just wide enough to stop these pests getting into your home.

LockLatch variations

The LockLatch range comes in three variations, the classic LockLatch, larger PetLatch and smaller MinILatch, each featuring the same robust design, but with different size openings so you can choose the one that is right for your needs. 


The original LockLatch is the most versatile option and able to be used in a wide variety of situations. This device allows for an opening of between 3.6 and 6.7 inches making it great for ventilation and general security, allowing cats to come and go as they please and as a window restrictor when on the smaller settings.


The PetLatch is a bit bigger than the classic LockLatch with an opening of 5.7 to 9 inches and is purpose built for pet access. This is the perfect pet door alternative for small to medium sized dogs.


The MiniLatch is the smallest of the three devices with an opening ranging from 1.8 to 3.1 inches between the footplates. This makes this device perfect for keeping pests out of the home, making windows safer for young children or to keep indoor pets inside.

No matter what your security needs are, LockLatch has got you covered.
