The correct measurement of the spindle size for a GU sliding door lock
Measuring the thorn size of a GU sliding door lock often goes wrong. This is because it is not always clear from which point the measurement should be taken. An incorrect measurement can lead to ordering an incorrect lock, resulting in installation problems.
What is the thorn size and how do you measure it correctly?
The thorn measurement is taken from the front plate of the lock to the center of the handle hole. In a lift-slide door, the lift-slide lock is often recessed 8 millimeters into the wood. The mistake that is often made is that measurements are taken from the front of the wood instead of from the front plate of the lock itself.
Steek size (PC size) for sliding bolt locks
"In addition to the thorn size, the pitch size (PC size) is also important. This is the distance between the center of the handle hole and the center of the cylinder hole. For all lift sliding locks, this measurement is standard at 69 millimeters. This means that all lift sliding fittings will fit this, regardless of the brand or type of lift sliding lock."
Avoid mistakes when measuring
To be sure of the correct sizing, it is important to always:
- Measure from the front cover and not from the front of the wood.
- To take the correct thorn size so that the lock fits well and functions correctly.
- The standard size of 69 mm to be used, so that the hardware always fits.
By following these measurement instructions, you prevent mistakes when purchasing a new GU sliding door lock and ensure a hassle-free installation.
