First, you need to measure the exact thickness of the door. Use a tape measure or vernier caliper to measure at the edge of the door to ensure that the measurement is accurate. This is because the lock body and lock tongue of the door lock need to adapt to the thickness of the door to ensure the stability and safety of the installation.
Second, understand the applicable door thickness range of the round interior door lock on the market. Usually, the packaging or instructions of the door lock will indicate its applicable door thickness range. For example, some door locks may be suitable for doors with a thickness of 35mm to 50mm, while others may be suitable for thicker doors.
Next, filter within the range of available door locks based on the measured door thickness. Make sure that the applicable door thickness range of the selected door lock includes your door thickness. If the door thickness exceeds the applicable range of the door lock, it may cause the door lock to be unable to be installed or unstable after installation.
In addition, when choosing a door lock, other factors need to be considered, such as lock core type, security, durability, etc. Make sure that the selected door lock not only meets the thickness requirements of the door, but also meets the security needs and usage scenarios.
Before installing the door lock, it is recommended to read the installation instructions of the door lock carefully and check whether all accessories are complete. During installation, follow the steps in the instruction manual to ensure that the round interior door lock is installed correctly and securely.
Finally, it should be reminded that if the thickness of the door is very special or beyond the normal range, a customized round interior door lock may be required. In this case, it is recommended to consult a professional door lock manufacturer or installer for more specific advice and help.
When choosing a round interior door lock, be sure to screen and match it according to the thickness of the door to ensure the installation effect and safety of the door lock.
