How to Install Door Handle
For how to install a door handle, I always thought it was relatively simple, with the same steps and accessories, even for different functions and styles, the steps are similar. Therefore, I can share with you how to install a door handle.
This is a set of accessories for the different functions of a door handle, and each accessory is labeled. If you have some experience in installing door handles, you can refer to them briefly. However, for friends without experience, carefully observe each step and follow the sequence to operate. I believe you can also install the door handle independently.
Step 1: Measure the thickness of the door and the length of the door edge distance.
Yes, you read it right. Initially, you didn't open a hole in the door, you needed to measure the thickness of the door. For door thickness, the standard is 1-3/8 "(35mm) or 1-3/4" (45mm), where 1-3/8 "is a common standard door thickness, especially for interior or lightweight doors, which are usually suitable for wooden or light steel doors in homes or offices, while 1-3/4" door thickness is generally used for commercial or entrance door types. After measuring the thickness of the door, you need to know that there are 2-3/8 "(60mm) and 2-3/4" (70mm) options for the locking length of the door handle, which is called "Backset" in professional terms, which is the distance from the center of the door hole to the door edge. If the door you purchased has already been perforated, you can consult the customer service of the salesperson to confirm the backset and thickness of the door; or if it is convenient, measure it yourself. When you purchase a door handle, the salesperson will also confirm these two data with you. These two data cannot be wrong. If one of them is not correct, the door handles you bought will not be compatible with your door, and even with after-sales service, it will waste a lot of time (if you like it, please pretend I didn't say it).
Step 2: Make a lock hole and a latch hole in the door.
After understanding the data of the door, we need to open a hole in the door. But perhaps you don't need to do it yourself, because some door salespeople will help you drill holes for free when you purchase the door, so you can pass this level without any damage. Congratulations (fireworks)! But there are inevitably exceptions, what if this service doesn't exist? So I still need to talk about it. The door handle was purchased from our website store, oh! Not only the door handle but also every door lock product comes with an opening hole diagram, just like this:
This is a standard opening diagram. Let's first focus on two backset data, which are the distances from the center of the door opening to the edge of the door. A dashed line is on the left side of these two data points. Fold along the dashed line and align it with the door edge accurately. The installation position of the door handle is generally 900-1000mm above the ground, and the specific height can be determined according to one's preferences and habits. Here are the pictures I took myself:
Then, based on the backset length of the door handle you purchased, select the corresponding center of the circle and mark it, or mark the position of the hole edge. After marking, remove the drawing and use a saw or other tool to drill holes. Drill holes with a diameter of 2-1/8 "(the standard hole diameter in the United States) slowly and vertically to prevent drilling deviation.
We have completed the production of the door hole. On the side of the door, we need to create a rectangular depression with a depth of 1/8 ", a length of 2-1/4", and a width of 1 "to place the face plate and a through hole with a diameter of 1" to place the lock tongue. Similarly, we need to attach the drawing to the side of the door and mark it with a tool to open the hole. Note that the center of the lock tongue hole needs to be at the same horizontal line as the center of the door handle hole. The two screws of the face plates can be drilled into 20mm with an electric drill, as the screw length is 20mm.
At this point, our door handle holes and face plate holes are completed, and the next step is the installation process.
Step 3: Install the door handle
We will use the disassembly pictures shown at the beginning for this step, and the serial numbers represent the components indicated in the pictures. Firstly, there is the door handle for privacy and passage functions (the privacy function door handle only has one more privacy pin (8) than the passage function). The first step in installing the door handles with these two functions is to install the tubular latch and face plate (1 and 2). Note that the latch tongue has a curved surface and a straight surface, where one side of the curved surface faces outside the door and the straight surface faces inside the door. Because our doors generally open inward, the curved side of the latch tongue facing outward can effectively reduce wear and tear on the latch tongue when it is closed, making it more durable. Moreover, the side of the latch tongue facing inward enhances the resistance to violent breaking and increases safety.
After fixing the tubular latch, insert the swift spine (5) into the tubular latch in any direction. The Swivel Spindle (5) has a small bead for fixing purposes. When inserted into the tubular latch, the bead can be pressed down to insert, and similarly, the same operation can be performed when removing it.
Next, insert the Interior lever (6) and Exterior lever (7) into the door opening and secure them with a through screw. Be careful to avoid mistakes in the handles of the inner and outer doors. The Exterior lever has two screw holes. If you turn these two handles upside down, outsiders can remove your lock, and then this lock will have no effect. Each door handle has two pairs of through screws, the shorter pair corresponds to a door thickness of 2-3/8 "(60mm), while the longer pair is used for a door thickness of 2-3/4" (70mm).
At this point, the passage function of the door handle is completed, and the privacy function door handle has an additional privacy-pin hole on the lock plate of the Exterior lever. Install the privacy pin (8) like a screw to have privacy function. The door handle with privacy function can be used on doors that require privacy space, such as bathrooms, toilets, or bedrooms.
The single dummy and double dummy door handles do not have the installation steps of the tubular latch and do not require opening holes. They only need to be fixed to the door with screws.
This is the step to installing the door handle on the door. I hope this is helpful to you. Thank you for watching.
