Multipoint Lock Faceplate Guide (Width, Shape, and How To Identify Yours)

A multipoint lock faceplate is the long metal strip that runs down the edge of the door and holds the locking components in place. It is the part you see when the door is open and is often referenced when identifying or matching a replacement lock.

What The Faceplate Is Used For

The faceplate positions and supports the locking points along the door edge, such as hooks, rollers, latches, or shootbolts. It also provides the mounting surface where the multipoint lock is fastened to the door.

Key Faceplate Characteristics To Check

• Faceplate width: measured straight across the visible strip on the door edge (in millimeters).
• Faceplate profile: flat styles versus wrap or U-channel styles that cover more of the door edge.
• End style: rounded (radius) ends or square ends.
• Finish: color or coating, which usually affects appearance more than fit.

Rounded (Radius) vs Square Faceplate Ends

Multipoint lock faceplates are finished with either rounded (radius) ends or square ends. This detail determines whether the faceplate will sit flush in the door edge.

• Radius ends: have curved corners and are commonly used when the door edge mortise is routed with rounded corners.
• Square ends: have sharp corners and require a square-cut mortise in the door edge.

A radius-ended faceplate will not fit cleanly into a square mortise without modification, and a square-ended faceplate will leave visible gaps in a rounded cutout. Because of this, the end style must match the door exactly.

If you want to visually confirm what a standard faceplate looks like, this example of a 16mm multipoint lock faceplate shows the faceplate width, profile, and end style as they appear on an actual lock.

Once these faceplate details are confirmed, they can be combined with other measurements using the multipoint lock measurement worksheet to narrow down the correct lock style.
