How to measure a tubular latch
When it comes to replacing or upgrading door latches, knowing the measurements of a tubular latch is essential. A tubular latch is a type of latch commonly used in interior doors, and its measurements determine if it will fit properly into the door frame.
The first measurement to consider is the overall length of the latch. This measurement is taken from the edge of the faceplate to the end of the latch bolt. Knowing the overall length will ensure that the latch fits snugly inside the door.
Another important measurement is the backset. This measurement refers to the distance from the edge of the door to the center of the handle or knob. Backsets typically come in 2 3/8 inches or 2 3/4 inches. It is crucial to get the correct backset measurement to ensure that the latch lines up with the strike plate on the door frame.
Lastly, the width of the faceplate should be considered. The faceplate is the metal plate that is visible on the edge of the door. The most common width for a tubular latch faceplate is 1 inch, but it can vary. Ensuring that the faceplate width matches the existing hole in the door is crucial for a proper fit.
Determining the Correct Size
In order to measure a tubular latch accurately, follow these steps:
- Remove the existing latch from the door. This is typically done by unscrewing the screws that hold the latch in place.
- Measure the backset, which is the distance from the edge of the door to the center of the latch.
- Determine the overall length of the latch. This can vary depending on the manufacturer, so it’s essential to measure it.
- Check the width of the latch. This can usually be found by measuring the distance between the two outer edges of the latch body.
- Inspect the latch faceplate shape. Tubular latches can have square, rounded, or beveled edges. Check the existing latch or the corresponding door recess to determine the correct shape.
- Examine the latch’s handle throw, which is the distance the latch extends and retracts when operated with a handle or knob. Measure this distance to ensure compatibility.
- Ensure that the latch’s strike plate, the metal plate that the latch engages with when the door is closed, aligns correctly with the door frame. Measure the dimensions of the existing strike plate or corresponding recess to verify compatibility.
- Note any additional features or requirements specific to your door, such as lock compatibility or specific finishes.
By accurately measuring the backset, overall length, width, faceplate shape, handle throw, strike plate dimensions, and any other specific requirements, you’ll be able to determine the correct size of the tubular latch for your door.
Choosing the Appropriate Length
When measuring a tubular latch, it is important to choose the appropriate length to ensure proper functionality and security. The length of the tubular latch refers to the measurement from the faceplate, the part of the latch that is visible when the door is closed, to the end of the latch body.
There are a few factors to consider when selecting the right length for a tubular latch:

Tip: If your measurement doesn’t exactly match standard backset dimensions, choose the closest measurement available and make any necessary adjustments during installation.
Remember to always double-check your measurements before purchasing a replacement tubular latch to avoid any fitting issues.
Understanding Backset Measurements
Backset measurements are an important aspect of measuring a tubular latch. The backset refers to the distance from the edge of the door to the center of the hole where the latch is inserted. It is crucial to understand this measurement in order to ensure that the latch will fit properly in the door.
Why Is Backset Measurement Important?
The backset measurement ensures that the latch lines up correctly with the hole in the door. If the backset measurement is incorrect, the latch may not function properly or may not fit at all. It is essential to measure the backset accurately to avoid these issues.
How to Measure Backset
Measuring the backset is a straightforward process. You will need a tape measure or a ruler with markings in inches. Follow these steps:
- Clean the area around the latch hole on the edge of the door to remove any dirt or debris that may interfere with the measurement.
- Locate the center of the latch hole. This is usually marked with a small indentation or a painted dot.
- Place the end of the tape measure or ruler on the edge of the door.
- Measure the distance from the edge of the door to the center of the latch hole. This is the backset measurement.
Most standard backsets are either 2-3/8 inches or 2-3/4 inches. It is crucial to determine the correct backset measurement for your specific latch before purchasing or installing it.
| Backset Measurement | Description |
|---|---|
| 2-3/8 inches | This is one of the most common backset measurements. It is often used for residential doors. |
