There’s no other product like LockLatch

While there are countless security devices available online, there is no option quite like LockLatch. This is largely due to the unique, patented design of this security device. The LockLatch range is designed in such a way that it can be easily fit onto any type of window or door in minutes, and it is this versatility that has led to it becoming a security feature in so many homes. The other major point of difference for LockLatch is how it locks your door or window in an open position. This means it has a wide range of benefits not offered by competing products relating to ventilation and the ability to control access to your home.

Keep Windows Open Securely

LockLatch can be quickly and easily fitted onto any type of window, whether they be large heavy double sash windows or windows with aluminium, wooden, uPVC or steel frames. Aside from supplementing your existing window locks, there are a number of reasons why you may want to keep your windows open but locked. Firstly, it is a great way to provide ventilation and the many other benefits that come from having fresh air in the home. It is also a great pet door alternative for cat owners, as it allows you to leave a window open without loss of security or peace of mind. It is also great as a window restrictor to make your home safer for young children, by preventing falls from second storey windows.

Keep doors open, yet secure 

LockLatch is also suitable for doors and the unique design means any type of door can be secured by this door lock. The benefits of being able to lock your door in an open position, mirror the benefits of its use as a window lock i.e. improved ventilation, pet access and improved security. It is also great for securing caravan doors and boat hatches, where ventilation is essential, in an open position. The LockLatch range is also a great way to prevent damage to doors caused by wind, such as when a door is slammed by the wind and damaged at the hinges.

Fits any Door or Window

The inherent versatility of the LockLatch devices is not something that can be overstated. The unique design means it can be fitted to any type of door or window. And when we say “any”, we mean any. From traditional wooden doors, to aluminium sliding doors the LockLatch range can be installed using the one-way security screws or rivets provided. It can also be used on shed doors, balcony doors, caravan doors and boat hatches. The same goes for windows, it doesn’t matter if you have casement, double-hung or awning style windows, you can be sure that LockLatch will fit.

An Alternative Pet Access Device

One of the most common uses for the LockLatch device is as a dog door or cat flap alternative. Because LockLatch allows you to control the size of your door or window opening it can be adjusted to allow your cat or small to medium dog to come and go as they please while making the gap small enough to keep intruders out. When used in this way LockLatch possesses a number of advantages over traditional solutions. It doesn’t require you to cut a hole in your door, and because it can be fitted to the door your pet prefers to use, it negates the need for training. The size of the opening can also be adjusted as your pet grows meaning you won’t need to reinvest if they get too big for the existing solution.

How Does the LockLatch Work?

The LockLatch device consists of three key components, each manufactured from C304 stainless steel. A U bolt, which allows for easy positioning on the frame; an adjustable steel arm with a locking pin; and the locking mechanism itself. The U bolt and locking mechanism are attached to the frame and the door respectively and the arm is then locked into the locking mechanism with the locking pin creating a secure connection between door and frame.

Highly Durable 

Because of its simple design, and tough C304 stainless steel construction the LockLatch device is highly durable and able to stand up to the rigours of long-term use. This includes being able to withstand prolonged exposure to the elements and the intentions of opportunistic criminals. While almost no security device can offer complete protection, we are so confident in the LockLatch that each device comes with a lifetime guarantee.
