Installing a lock on an adjustable door within the 60 - 70mm range might seem like a daunting task, but with the right guidance and tools, it can be a straightforward process. As a supplier of Adjustable Door 60 - 70mm, I've helped numerous customers through this installation journey. In this blog post, I'll walk you through the steps to ensure a successful lock installation.
Step 1: Gather the Necessary Tools
Before you start the installation process, it's crucial to have all the required tools at hand. Here's a list of tools you'll need:
- Screwdriver set (both flat - head and Phillips - head)
- Drill with appropriate drill bits
- Measuring tape
- Pencil
- Chisel
- Hacksaw (if needed for minor adjustments)
Step 2: Choose the Right Lock
There are different types of locks available for adjustable doors in the 60 - 70mm range. Two popular options are the Tubular Deadbolt and the Tubular Private Latch.
The Tubular Deadbolt offers enhanced security as it has a solid bolt that extends into the door frame, providing a more robust locking mechanism. It's ideal for exterior doors or areas where high - level security is required.
On the other hand, the Tubular Private Latch is more suitable for interior doors, such as bedrooms or bathrooms. It provides privacy by allowing the door to be locked from the inside, but it may not offer the same level of security as a deadbolt.
Step 3: Measure the Door
Accurate measurements are key to a successful lock installation. Use a measuring tape to measure the thickness of the door. Since we're dealing with adjustable doors in the 60 - 70mm range, double - check to ensure your door falls within this specification.
Next, measure the distance from the edge of the door to the center of the existing hole (if there is one) or the desired location for the lock. This measurement will help you position the lock correctly. Mark the center point on the edge of the door with a pencil.


Step 4: Prepare the Door
If you're replacing an existing lock, remove the old lock using a screwdriver. Unscrew the screws on the faceplate and the strike plate on the door frame. Carefully take out the old lock components.
If you're installing a lock on a new door, you'll need to create the necessary holes. Refer to the lock's installation instructions for the correct hole sizes. Use a drill with the appropriate drill bit to create the holes for the lock cylinder and the latch.
For the strike plate on the door frame, use a chisel to create a recess. This will ensure that the strike plate sits flush with the door frame. Make sure the recess is the right size and depth according to the strike plate's dimensions.
Step 5: Install the Lock
Insert the lock cylinder into the hole on the edge of the door. Align the holes on the cylinder with the holes on the door. Secure the cylinder in place using the provided screws.
Next, install the latch mechanism. Slide the latch into the hole on the edge of the door and align it with the lock cylinder. Tighten the screws to hold the latch in place.
Step 6: Install the Strike Plate
Place the strike plate on the door frame at the position where the latch will engage. Use a pencil to mark the screw holes on the door frame. Drill pilot holes at the marked locations.
Align the strike plate with the pilot holes and secure it to the door frame using screws. Make sure the strike plate is level and that the latch fits smoothly into it.
Step 7: Test the Lock
Once the lock and strike plate are installed, test the lock to ensure it works properly. Insert the key into the lock cylinder and turn it. The latch should extend and retract smoothly. Close the door and check if the latch engages with the strike plate correctly. If there are any issues, such as the latch not fitting properly or the lock being difficult to turn, make the necessary adjustments.
Step 8: Make Adjustments
If the lock doesn't operate smoothly or the latch doesn't align with the strike plate, you may need to make some adjustments. You can use a hacksaw to trim the latch or the strike plate slightly if they are not the right size. You can also adjust the position of the strike plate on the door frame by loosening the screws and re - positioning it.
Step 9: Final Checks
After making any adjustments, test the lock again to ensure it functions correctly. Check the security of the lock by trying to open the door from the outside without using the key. Make sure the door closes and locks securely.

Installing a lock on an adjustable door in the 60 - 70mm range is a manageable task if you follow these steps carefully. Remember to choose the right lock for your needs, take accurate measurements, and follow the installation instructions provided with the lock.
