Jackloc Pro-Twist Window Restrictor

The Jackloc Pro-Twist Window Restrictor has a 200mm restrictor cable that stops your window from opening farther than 100mm, sufficient for ventilation, but wide enough your child can climb through! The push and turn lock makes it easy to open your window fully without a key.

Who Can Benefit from the Jackloc Pro-Twist Window Restrictor?

A significant portion of accidental deaths are caused by falls, and in households with children it's particularly important to prevent your little one from leaning too far out of the window! At the same time, the restrictor can help prevent burglaries as an intruder would need bolt cutters to break the 3mm thick reinforced cable before they could fully open your window.

Why the Jackloc Is Perfect for Twins

Once your little one is up and about, 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 Restrictor can give you one fewer thing to worry about.

Will the Jackloc Pro-Twist Window Restrictor Fit My Window?

The Jackloc Pro-Twist Window Restrictor is designed to fit any type of window and material, including frames made of wood, uPVC, aluminium, steel or composite. The versatility of the design means you don't have to shop around to find different window restrictors for all of the windows in your home.

Fitting Instructions for the Jackloc Pro-Twist Window Restrictor

To install your Jackloc Pro-Twist Window Restrictor, place it in the desired position against your window and window frame. Mark the screw holes with a pencil, then screw the resistor in place using a drill. For a demonstration, please watch this short video:

How Much Weight Can This Window Restrictor Hold?

According to the British Standard, window restrictors should have a holding force of 500 newtons, the equivalent weight being 8 stone. Jackloc cable restrictors can hold over 4 times this amount on frames made of steel aluminium or timber, so you can be confident that the restrictor will not break even if someone accidentally leans against the window.

Do I Have to Use the Screws Provided?

The Jackloc Pro-Twist Window Restrictor comes with 4 hardened steel security clutch screws for maximum strength hold. However, these cannot be removed once they are drilled in unless a tungsten carbide drill is used.

If you'd like to remove the restrictor at a later date, we would recommend using your own screws instead. Please ensure they correctly fit the restrictor and are suitable for your window.

What Colours Are Available?

The Pro-Twist window restrictor can be purchased in four different colours: standard white, black, brown or dark grey. You can select your preference using the drop down box at the top of the page.
