Multipoint Lock Overall Length (How To Measure Faceplate Length)
Multipoint lock overall length (also called faceplate length) is the measurement of the long metal strip that runs along the edge of the door. It is measured from the very top of the faceplate to the very bottom and helps confirm whether a replacement lock will physically fit the door.
Key Takeaways
- Overall length = faceplate length: measure the metal strip, not the door.
- Measured top to bottom: include the full ends of the faceplate.
- Used to confirm fit: wrong length can leave gaps or misaligned lock points.
What Overall Length Means
Overall length is the total height of the multipoint lock faceplate. Even though many multipoint locks run nearly the full height of the door, the correct measurement is always taken on the lock itself.
How To Measure Overall Length
- Open the door and locate the faceplate on the door edge.
- Measure from the very top of the faceplate to the very bottom.
- If the ends are rounded, measure to the furthest points.
Common Mistake
Overall length is not the same as door height. Different multipoint locks can have different faceplate lengths even on the same size door.
What To Check Next
Overall length helps narrow down the correct lock, but it is only one of several required measurements. To identify the correct replacement, gather all measurements together using the multipoint lock identifier.
