What makes LockLatch so unique?

When it comes to understanding what makes the LockLatch range so unique and effective, we need to start by looking at the design of the device itself. It is the brutal simplicity of the patented design, which enables the device to be fitted to any type of window or door, making it one of the most versatile security solutions on the market. It is also this unique 3 part design which allows each piece to be constructed from C304 stainless steel to ensure a device so durable that each one comes with a lifetime guarantee.

Keep Windows Open Securely

Probably the most important feature of LockLatch is the ability to keep your windows (and doors) open while still ensuring they are securely locked. This is perfect for homes and spaces that are stuffy, have mould problems or just need a bit more fresh air. There are many wide-ranging health benefits linked to better home ventilation and LockLatch represents one of the simplest ways to keep your home well ventilated and secure. It is also great as a window restrictor for child safety, as well as keeping animals such as baboons, monkeys or the neighbours pets from entering your home.



Keep doors open, yet secure

Because of the unique design, LockLatch can also be used on a variety of doors from traditional wooden doors to aluminium, UPVC and steel-framed doors. There are many instances when you might want to leave your door open, whether it is to let fresh air in or as a pet door alternative to allow your favourite pet to come and go as they please. It can also be used to prevent wind damage to doors that need to be left open, as it prevents the wind from slamming them closed or blowing them open and off their hinges.

Fits any Door or Window

We have already mentioned the versatility of the LockLatch device, but it is something that bears repeating. The design means LockLatch can fit on any type of window from heavy wooden double-sash windows to modern aluminium windows. The same rule applies to doors, if you have an entry point that needs to be secured then LockLatch can be installed in a few minutes with only basic DIY knowledge.

Pet Access Device 

One of the most popular uses of the LockLatch device (and one that it is uniquely suited for) is as an alternative to a traditional dog door or cat flap. For the owners of smaller dogs, LockLatch allows you to keep your door open wide enough to let your dog in or out, but still not open enough to let an intruder in, providing a great dog door alternative. The same applies to cats and windows, as a cat flap alternative, LockLatch allows you to leave your cat’s favourite window open without worrying about opportunistic break-ins.

How Does the LockLatch Work?

LockLatch works by connecting the door or window that needs to be secured to its frame with an adjustable C304 stainless steel arm. The size of the opening can be tailored to your needs and the locking pin is then secured into the locking mechanism. If you wish to close your window entirely you simply unlock the locking mechanism and remove the locking pin to allow the window to open or close as normal. This ability to quickly and easily adapt the LockLatch to your needs means it’s perfect for keeping pets in or out, and improving child safety on second floor balconies.

Highly Durable

The LockLatch has three key components: the Ubolt, which fits onto the door or window, the adjustable arm, and the locking mechanism. Each of these components is made from C304 stainless steel which means they are able to withstand the elements and the attentions of opportunistic burglars or thieves. This durability is one of the reasons why LockLatch comes with a lifetime guarantee, which brings us to our next feature.
