Radius Cover Plate for 19mm and 22mm RTD Lever on Backplate Latch

The Radius Latch Backplate for RTD Levers is the definitive architectural solution for non-locking passage doors in high-traffic commercial, healthcare, and educational environments. Specifically engineered to house 19mm and 22mm Return-to-Door (RTD) safety levers, this Radius Latch Backplate features a “plain” face with no keyhole or thumbturn cut-outs, providing a clean, minimalist aesthetic that perfectly matches the locking hardware used throughout a facility.

The radius profile—characterized by its elegantly curved top and bottom—is a strategic design choice that eliminates sharp 90-degree corners, significantly reducing the risk of accidental snags in busy corridors.

In professional ironmongery, a “Latch” backplate is used on doors that require only a handle to operate, such as those leading to storage areas, communal hallways, or internal office partitions.

Key Performance Benefits

• • Total Snag Prevention: In emergency exit routes, hospital wards, or busy school corridors, sharp 90-degree corners are a significant hazard. The radius profile removes these edges, ensuring that clothing, medical straps, or equipment can glide over the hardware without catching.

  • Aesthetic Uniformity: Latch backplates are “plain” (no keyhole or thumbturn). By using a radius profile that matches your Euro and Bathroom locking plates, you create a seamless visual “line” across a facility, regardless of the door’s function.

  • Infection Control & Hygiene: Stamped from Grade 304 Stainless Steel, these plates are non-porous and resistant to aggressive chemical disinfectants. The curved edges also prevent the accumulation of dust and bacteria that typically settle in the corners of traditional rectangular hardware.

  • Tamper-Resistant Engineering: The decorative radius cover fits securely over a structural steel sub-base that is bolted through the door. This “sandwich” fixing method hides all mounting screws, making it nearly impossible for unauthorized personnel to remove the hardware in public areas.

Installation Pro-Tip: The “Corridor Alignment”

To ensure a professional finish across a long hallway:

1. Mount the sub-chassis using the spindle as your primary centering tool.

2. Use a spirit level along the vertical edge of the sub-chassis before marking your bolt-through holes.

3. When installing the second side, ensure the bolts pass cleanly through the door and the latch case without forcing.

4. Once the sub-chassis are perfectly vertical and tight, “snap” the decorative covers on. If the covers don’t click easily, check that your screw heads are perfectly flush—even a 1mm protrusion can prevent the friction-fit clips from engaging.
