FAQ
What materials are these security products made from?
These door and window restrictors are manufactured from uPVC-compatible plastic, designed to be compatible with standard uPVC frames. Ensure compatibility before installation.
Are these suitable for all types of doors and windows?
While compatible with most uPVC frames, we recommend checking the dimensions against your specific door or window size to ensure a snug fit and optimal security. They are not designed for heavy-duty timber frames.
How easy are these to install?
Installation is straightforward and doesn’t require specialist tools. Most users will find it simple to install the restrictors with basic hand tools – typically a screwdriver.
What security level do these provide?
These offer a deterrent against opportunistic entry but are not a replacement for a high-security lock. They work best when used in conjunction with other security measures.
Are these weatherproof?
The uPVC-compatible plastic is designed to withstand typical UK weather conditions, including rain and frost. However, avoid prolonged exposure to direct sunlight or extreme temperatures.
What tools do I need for installation?
You’ll typically only require a standard Phillips head screwdriver for installation. A small measuring tape can also be helpful for accurate placement.
Are there any specific limitations on their use?
These are best suited for preventing forced entry through doors and windows, not for resisting sustained attacks. They should not be used as the sole security measure.
What is the lifespan of these products expected to be?
With proper care and maintenance, these plastic restrictors can typically last 3-5 years in a standard UK home environment. Regular inspection for wear and tear is recommended.
Can I use these on sliding doors?
While possible, these are primarily designed for hinged doors and windows. Sliding door security often requires more specialized solutions.
What happens if the plastic becomes damaged?
If the plastic components become damaged, they should be replaced immediately. Replacement parts are not included – check with the manufacturer or Amazon for available replacements.
