What exactly is door and window hardware?

Door and window hardware refers to all components used to open, close, and secure doors and windows. This includes hinges, locks, door handles, window fasteners, and security fittings. Quality hardware is important for both ease of use and burglary prevention. We offer a wide range of door and window hardware.

What types of locks are available for doors and what are their benefits?

There are various types of locks, such as cylinder locks, multi-point locks, mortise locks, and pin locks/additional locks. Cylinder locks are the most common and easy to replace. Multi-point locks offer extra security by locking the door at multiple points. Choose the right option for your situation. Need help? Contact us, we’re happy to provide free and personal advice.

How do I choose the right hardware for my home?

When choosing door and window hardware, consider security (e.g., SKG quality mark), the application (indoor or outdoor), material (stainless steel, aluminum, etc.), and the style. Always choose burglary-resistant hardware with reliable quality. Our customer service is ready to help you with expert advice.

What is the purpose of security fittings on doors?

Security fittings protect the lock and cylinder against burglary methods such as drilling, snapping, or pulling. They are often required for burglary-resistant measures like the Dutch Police Quality Mark for Safe Living and greatly enhance the security of your front door.

What is the difference between hardware for windows and doors?

Window hardware is usually lighter and allows for ventilation features like casement stays or window fasteners. Door hardware is more robust and designed for heavy use and better burglary resistance, especially for exterior doors.

Which quality marks are important for hardware?

The SKG quality mark is the most well-known and indicates how burglary-resistant a product is (1, 2, or 3 stars). The Police Quality Mark for Safe Living (PKVW) also requires certified hardware. CE marking may also be relevant for building-related applications. You can find a complete overview of applicable certifications on this page.

How do I properly maintain my door and window hardware?

Clean locks and fittings regularly with a soft cloth, remove debris from hinges, and lubricate moving parts with a special lubricant. Check for wear or loose parts regularly and replace them in time if needed.

What does the SKG mark mean on locks and fittings?

The SKG mark indicates how well a lock, cylinder, or fitting resists burglary. SKG** means medium resistance and SKG*** indicates extra heavy burglary resistance. For exterior doors, SKG** is typically the minimum recommended.

When should I replace my lock or cylinder?

Replace a lock or cylinder when it is worn, defective, after a burglary (or attempt), or if you've lost your keys. It's also advisable when moving into a new home or upgrading to a more secure system.

What is a multi-point lock and is it more secure than a regular lock?

A multi-point lock secures a door at several points simultaneously (usually top, middle, and bottom). This makes it much harder for burglars to force the door open. It certainly provides more security than a single-point lock.

Is there a difference between hardware for interior and exterior doors?

Yes, exterior doors require heavier and burglary-resistant hardware, often with the SKG mark (at least SKG** recommended). For interior doors, simpler hardware without extra protection is usually sufficient, unless it's a storage or utility access door.

What is core pull protection and why is it important?

Core pull protection prevents burglars from pulling the cylinder out of the lock, a common method of burglary. Fittings with this feature include a hardened metal plate that protects the cylinder.

Can I install hardware myself or do I need a professional?

Simple components like door handles and window fasteners can often be installed by yourself. For replacing a cylinder lock or installing a multi-point lock, it's advisable to hire a professional for optimal security. You can find installation guides on this page. Need help installing your hardware? Contact us and we’ll arrange a professional to install everything for you.

What types of window fasteners are available?

There are several types of window fasteners, such as espagnolette fasteners, tilt-and-turn mechanisms, and casement stays. Some can be locked with a key, offering extra burglary protection.
