What is the Purpose of the Faceplate on a Door Lock?
The main purposes of the faceplate on a door lock include:
- Covering and protecting the lock mechanism – The faceplate covers the inner workings of the lockset, helping keep out dust, debris and moisture.
- Providing an attractive appearance – Faceplates come in many decorative styles and finishes to coordinate with the door hardware and surrounding decor.
- Allowing proper door clearance – A round or beveled faceplate provides clearance so the door can open and close without hitting the plate.
- Hiding unsightly holes – The plate covers the bolt holes and mounting screws needed to install the lockset.
Types of Door Lock Faceplates
There are several common types of faceplates used on door locks:
- Round/Circular faceplates – These classic round plates provide the needed clearance for the door swing. They come in standard diameters like 2-1/4″, 2-3/8″, or 2-3/4″.
- Square corner/Beveled faceplates – Square cornered plates have angled edges to allow clearance. Beveled faceplates have an angled curved profile.
- Rectangular faceplates – Straight edged rectangular plates sit flat against the door. These are more common on mortise locks or non-turning lever handles.
- Ornamental/Decorative faceplates – These feature stylized shapes, curves and detailing for aesthetic appeal.
Materials Used for Door Lock Faceplates
Typical materials used to make lock faceplates include:
- Steel – Steel faceplates provide strength and durability at an affordable cost in finishes like satin, bronze, nickel, or black.
- Brass – Solid brass plates offer a classic upscale look. Finishes like polished brass, antique brass, and oil-rubbed bronze are common.
- Zinc Alloy – Die cast zinc alloys like zamak can be made into ornate decorative faceplates.
- Wood – Wood faceplates made from oak, maple, or other species provide a natural, rustic or Old World look.
- Glass/Crystal – For unique high-end decorative locks, etched glass or cut crystal faceplates can be used.
Faceplate Sizes for Common Door Lock Types
Standard faceplate sizes vary by the type of door lock mechanism:
| Lock Type | Standard Faceplate Size |
|---|---|
| Cylindrical Locksets | 2-1/4″ or 2-3/8″ diameter |
| Mortise Locks | 2-3/4″ x 1-1/4″ rectangle |
| Deadbolts | 2-1/8″ x 1-1/4″ rectangle |
| Knobsets/Levers | Various shapes and sizes |
However, many faceplate sizes are interchangeable if the bolt holes line up. Adaptor plates are also available to convert between sizes.
How to Change a Door Lock Faceplate
Replacing an old or damaged door lock faceplate is an easy DIY project. Here are the basic steps:
- Remove the existing faceplate screws. This allows you to separate the faceplate from the door lock assembly.
- Carefully pull the old faceplate straight off the door to avoid damaging the lockset.
- Select the replacement faceplate. Verify it aligns with the bolt holes and fits the lockset.
- Position the new faceplate over the lock assembly, lining up the screw holes.
- Install the screws to securely attach the faceplate to the door.
- Check that the lock functions properly with the new faceplate installed.
Be sure to select a replacement faceplate made for the specific brand and style of your door lock. Taking proper measurements helps ensure an accurate fit.
