At the Mother & Baby Awards 2020, the Jackloc Pro-5 Key-Locking Window Restrictor won the Silver award in the category Best Safety Product.

How Does the Pro-5 Window Restrictor Work?

The Jackloc Pro-5 features a simple and effective design that allows for easy window baby proofing. The restrictor consists of two parts that are connected via a cable, one part that you attach to the window and one part that you attach the the window frame. The cable stops the window from opening further than you would like, preventing accidents.

How Safe Is the Jackloc Pro-5?

The Jackloc Pro-5 Window Restrictor is designed to withstand a force of up to 3600 Newtons – to put this in perspective it takes 3600 Newtons of force to lift 367kg (or over 57 stone) so, unless your child can do that, they'll not be able to forcibly break the window restrictor. The restrictor can be detached via the supplied key, meaning that the window can be fully opened at your discretion but only for those with access to the key.

As well as having a reinforced zinc cable, the Jackloc Pro-5 features a patented five-disc locking barrel that makes it more childproof. While other models of window restrictor include a turning mechanism that could be undone by curious hands, the Pro-5 will only release when opened with the supplied key.

Why the Jackloc Is Perfect for Twins

Once your little one can cruise, there's no telling where they can end up, and this includes in potentially dangerous situations. With two children getting into mischief, peace of mind is even more important, and the Jackloc Key-Locking Restrictor can give you one fewer thing to worry about.

Is the Jackloc Pro-5 Easy to Install?

While the Jackloc Key-Locking Restrictor provides you with a professional level of protection, it is easy to install with some rudimentary DIY knowledge. Please watch the video below for an explanation of how to install the restrictor.

For more information, we would recommend reading the technical data sheet (please note that the data sheet refers to the product by its previous name, the Jackloc Mk2 – the information is still relevant for this version).

Which Windows Can the Jackloc Be Used With?

The Jackloc is designed to be used with as many styles of window as possible and it is suitable to be fitted to the following materials:

  • uPVC (unplasticised polyvinyl chloride)
  • Wood
  • Aluminium
  • Steel
  • Composite Materials

Available in Multiple Colours

To help the Jackloc Pro-5 Window Restrictor fit in with your current decor, it is available in the following colours:

  • White
  • Black
  • Brown
  • Dark Grey

Why Should I Trust the Jackloc Pro-5?

It's understandable to be apprehensive where your child's safety is concerned. To ensure that the Jackloc meets all of the rigours that it is designed for, it has been tested to the following European standards:

  • EN 14351-1:2006 – Exceeded pass result on uPVC, wood, aluminium and steel windows
  • EN 13126-5:2001 – Achieved pass tests for mechanical load, impact, percussion and cutting test for a force of 3600 newtons
  • BS 6375:2 1987 – Exceeded force tests by 100 - 400%
  • UKAS Salt Spray Test – Tested in accordance with ASTM B117-07 and evaluated to EN 1670:2007

The above are regulations for the durability and design of windows and doors, and associated products. These rigorous tests have been conducted to ensure that the Jackloc performs to the required level.

Is the Jackloc Easy to Remove?

The Pro-5 Window Restrictor is supplied with four size-8 security clutch screws. Once these have been fitted, they cannot be easily unscrewed. If you would prefer to remove the restrictor once your child reaches a certain age, we would recommend using different screws (please refer to your windows manufacturer for information on the best option).

Made in the UK

To ensure the highest possible level of quality, Jackloc products are designed, engineered, manufactured and tested in the UK.
