Cover Plate for 19mm and 22mm RTD Lever on Backplate Lock 57mm

Depending on the function of your door, the style of cover plate you require will vary. Architectural plates are typically categorized by the “cut-out” they feature:

• Euro Profile Cover: Specifically shaped to fit around a Euro cylinder. These are essential for preventing “lock snapping” by ensuring the cylinder is tightly encased and flush with the door surface.

• Standard Keyhole Cover: A traditional “lever” shape cut-out for standard mortice keys. Ideal for heritage properties and internal timber doors.

• Blank Cover Plate: A solid plate with no holes, used to neatly cover old hardware points when a door is being repurposed or a lock is removed.

• Thumbturn/Privacy Cover: Features a circular cut-out for a bathroom privacy turn or emergency release.

Why Choose “Push-On” Cover Plates?

Modern architectural hardware often uses a two-part system. A plastic or metal sub-chassis is screwed directly into the door, and the decorative Cover Plate is then pushed or clicked over the top.

1. Concealed Fixings: No visible screw heads, providing a “screwless” minimalist look.

2. Ease of Maintenance: The plate can be popped off with a flat-head screwdriver if you need to tighten the handle or lubricate the lock.

3. Color Swapping: You can easily update the finish of your door hardware (e.g., from Chrome to Black) by simply swapping the cover plates without redrilling the door.

Recommended Hardware

For a durable, contemporary finish, the Satin Stainless Steel Cover Plate is the industry standard for commercial offices and high-traffic public areas. It is corrosion-resistant and incredibly easy to clean.

If you are renovating a period home, the Solid Brass Euro Cover provides a heavy, premium feel. It is hot-forged for durability and available in polished or antiqued finishes to match traditional decor.

Installation Pro-Tip: The “Alignment” Check

When installing cover plates, ensure the lock or handle is perfectly centered within the cut-out. If the plate is slightly off-center, the key or thumbturn may rub against the metal, causing resistance or scratching the finish over time. Always test the operation of the lock before clicking the push-on cover into its final position.

A Cover Plate (also known as an escutcheon or rose cover) is a versatile architectural component used to provide a clean, finished appearance to door hardware. Its primary purpose is to conceal structural fixings, rough-cut holes, or internal mechanisms, protecting them from dust and tampering while enhancing the aesthetic of the door.Beyond simply “hiding a hole,” a high-quality cover plate provides structural reinforcement to the door face and protects the internal locking mechanism from environmental debris and tampering.

Pro-Tip: The “Click” Test

When installing a push-on cover plate, ensure you hear a distinct audible click. This confirms that the internal spring-tension clips have engaged with the sub-chassis. If the plate feels loose or “rattles,” check that the sub-chassis screws are driven perfectly flush; a protruding screw head is the most common reason for a cover plate failing to snap into place correctly.
