Key-locking window restrictor with a clever difference — the included bracket fits behind your existing window handle using the handle's own screws, so there's no drilling into the frame. An alternative fixing plate is included for windows where the bracket method doesn't suit.

Key benefits
  • No-drill fitting — hidden bracket mounts behind your existing handle
  • 100kg tested cable — restricts opening for child-safe ventilation
  • Key-locking release — 2 keys and full fixing kit supplied
Product overview

The smarter way to install a window restrictor.

Most window restrictors require you to fix directly into the window frame.

This one offers something better.

The secret is the bracket.

Included in the box is an innovative metal mounting bracket designed to fit behind your existing window handle.

Simply remove the handle screws, position the bracket behind the handle and refit the handle using the existing fixings. The bracket becomes securely mounted while providing a neat, professional installation with minimal effort.

For windows where this installation method isn't suitable, an alternative fixing plate is also included, giving you complete installation flexibility.

Designed with installers in mind.

Whether you're a professional installer, landlord, housing provider or homeowner, this clever mounting system makes installation quicker and easier while delivering a clean, high-quality finish.

Secure when locked. Simple when unlocked.

The 230mm locking cable safely restricts how far a window can open while allowing everyday ventilation. When unrestricted access is required, simply unlock the cable with one of the supplied keys and disconnect it in seconds.

Frequently Asked Questions

Remove your existing window handle screws, sit the bracket behind the handle, and refit the handle using the same fixings. The bracket is clamped securely in place by the handle itself — no new holes in your window frame.

It's designed around the standard screw fixings used on most uPVC and aluminium window handles. If your handle or window type doesn't suit the bracket, the included fixing plate lets you install the restrictor conventionally instead — so the kit covers you either way.

Yes — the steel cable is tested to a 100kg (M1) load force and restricts the window to a safe ventilation gap. It's the type of key-locking restrictor used in schools, care settings and rented properties to meet safety requirements.

Yes. Unlock the cable with one of the two supplied keys and disconnect it in seconds for cleaning or full access — then clip it back in and lock it. Keep the restrictor locked wherever child safety is the priority.

Installed with the handle bracket, nothing is drilled or screwed into the frame itself — the restrictor mounts via the existing handle fixings, which is why installers and landlords like this method.
