For door hardware with a keyhole, the distance between the handle and the keyhole is the determining factor. In the Netherlands, 56 mm is the standard for interior doors, but always measure this before ordering. Do you have an older door? Then door hardware with a backplate is often the smartest choice. This neatly covers the lock hole recess. Tip: Use our free Measuring Guide to ensure you order the correct door hardware!
Frequently asked questions about Door fitting with keyhole
What is the standard distance for door hardware with a keyhole?
In most Dutch homes, the center-to-center distance for interior doors with a keyhole lock is 55 mm (SL55). In Germany, 72 mm is the standard. Always measure from the center of both holes and use our Measuring Guide!
How do I tell the difference between a keyhole and a cylinder hole?
A keyhole (SL) is narrow and shaped like a traditional bit key. A cylinder hole (PC) is wider and has a rounded top and a narrow bottom, specifically designed for profile cylinders.
Can I use rosette door hardware for a door with a keyhole?
Yes, you combine a rosette door handle with a separate escutcheon. The big advantage is that the distance between the handle and the keyhole is less critical during installation, because you install the two components separately.
Are door fittings with a keyhole supplied with a key?
No, the key comes with the mortise lock already installed in the door. We can, of course, supply the correct mortise lock directly. Simply order it via the related products on the product page!
Does every door fitting fit every door?
No, due to the varying bolt spacings, not every fitting fits every lock. Also, always check the door thickness carefully and measure it beforehand to avoid surprises!
Door hardware with keyhole
Are you looking for door hardware that perfectly matches your doors and locks? Our range of door handles on backplate with keyholes offers the perfect combination of aesthetics and functionality for any room that needs to be lockable. The right choice depends on one crucial detail: the center-to-center distance of your lock.
How to choose the right center-to-center distance for your door hardware
The center-to-center distance of door hardware is the distance between the lever spindle, used to operate the door handles, and the locking mechanism. This is also commonly referred to as the PC size of door hardware. Correctly measuring this distance is essential to ensure your new door hardware with keyhole fits your door.
How to measure the center-to-center distance of your door:
Measure the distance in millimeters from the center of the handle hole (the middle of the square spindle that the door handle passes through) to the center of the keyhole or cylinder hole.
Please note: Measure accurately to avoid mistakes. Then, choose the correct center-to-center size from our wide range of door hardware that matches the distance you have just measured.
Center-to-center distances explained
Our door hardware with keyhole is available in four common center-to-center sizes. Each size is intended for a specific type of lock:
SL56 and SL72 (Keyhole):
These center-to-center sizes are intended for interior doors where a traditional keyhole (bit key) is present in the backplate. This is often used with older locks or standard room doors.
SL56 and SL72 refer to the distance in millimeters between the handle and the keyhole.
PC55 and PC72 (Cylinder lock):
The designation 'PC' stands for Profile Cylinder. These center-to-center sizes are intended for doors where a modern cylinder lock is integrated into the backplate. This is the standard for exterior doors, but is also increasingly used for interior doors that must lock with a unique key, such as an office or storage room.
PC55 and PC72 refer to the distance in millimeters between the handle and the center of the cylinder.
Is the right center-to-center size not listed here? That is very frustrating, but there is a solution! In that case, choose separate door escutcheons in combination with door handles on rose. This gives you much more flexibility with the individual elements!
