Cover Plate for 19mm RTD Lever on Short Backplate Lock 57mm 45mm x 180mm Polished Stainless Steel Durable Replacement

Forged from high-grade 304 Stainless Steel and hand-polished to a mirror-like brilliance, this Polished Stainless Short Backplate provides the luxury aesthetic of polished chrome with the superior mechanical durability and corrosion resistance of structural steel.

In architectural specification, Polished Stainless Steel is the preferred choice for luxury office developments, boutique hotels, and coastal properties where salt-air oxidation or high-traffic wear is a constant threat.

• Mirror-Finish Aesthetics: The high-gloss, reflective surface provides a clean, contemporary look that complements polished chrome or bright nickel hardware. Unlike chrome plating, which is a surface coating that can peel or flake over time, this finish is achieved by polishing the base steel itself, ensuring a lifetime of brilliance.

• Superior Infection Control: The non-porous, polished surface is exceptionally smooth, making it difficult for bacteria and pathogens to adhere to the metal. Polished Stainless Short Backplate  makes it an ideal specification for private healthcare facilities, laboratories, and high-end hospitality venues requiring rigorous hygiene and sterilization protocols.

• Architectural Flexibility (180mm Profile): Short backplates are the primary solution for modern doors with narrow stiles or those featuring decorative glazing beads. By reducing the vertical footprint, these Polished Stainless Short Backplate sit comfortably on the door leaf without overlapping with glass moldings or fire-rated vision panels, preserving the door’s structural integrity.

• Concealed “Snap-On” Assembly: Security and aesthetics are balanced via a two-part assembly. A heavy-duty steel sub-base is bolted through the door to provide structural strength and a “sandwich” grip. The polished 180mm cover then “snaps” over the top, hiding all fixings. This creates a minimalist aesthetic and makes the hardware tamper-resistant in public environments.

Technical Specifications & Performance of Polished Stainless Short Backplate

To ensure long-term performance in demanding environments, Polished Stainless Short Backplate are engineered to accommodate both standard and safety-rated lever diameters.

Recommended Hardware Pairings

To maintain a cohesive architectural theme across your facility, consider these matching components:

• 19mm Polished RTD Lever: A matching Return-to-Door safety lever ensures DDA compliance and a rattle-free fit within the precision-machined bore.

• Polished Stainless Hinges: Use Grade 304 ball-bearing hinges in a matching mirror finish to ensure the door operates as smoothly as the handle feels.

• Mirror-Finish Escutcheons: For secondary doors without handles, use matching polished stainless rose covers to maintain the design theme across the entire floor plate.

Installation Pro-Tip: The “Final Reveal”

Because a polished surface highlights every fingerprint and misalignment, a precise installation is essential for a high-end finish.

1. Marking the Sub-Chassis: Use a paper template or the sub-chassis itself to mark your bolt-through holes. Misaligned holes can cause the lever to “stick” or the plate to sit crooked.

2. The “Sandwich” Grip: Tighten the M4 or M5 bolts until the sub-chassis is firm against the door. On hollow-core doors, avoid overtightening to prevent “crushing” the door leaf.

3. The Audible Click: When snapping the decorative cover onto the sub-base, ensure you hear the “click” on both the top and bottom. This confirms the plate is seated flush against the door.

4. The Microfiber Finish: Once installed, wipe the surface with a microfiber cloth and a drop of surgical spirit or glass cleaner to remove installation oils and fingerprints, revealing the deep mirror shine.
