Flush plate M57-N-M by ALCA — metal control button for concealed WC systems, nickel-mat finish

The Flush plate M57-N-M by ALCA is a metal control button designed for concealed (in-wall) WC flushing systems. With a nickel-mat finish and compact form, this flush plate serves as a durable user interface for activating built-in toilet cistern mechanisms. It is intended for installation as a visible control on finished bathroom walls where a simple, sturdy actuator is required for single- or dual-flush concealed cisterns compatible with standard mechanical linkages.

Advantages

The metal construction provides higher resistance to daily use and mechanical wear compared with most plastic plates, while the nickel-mat surface offers a neutral, corrosion-resistant appearance that blends with many bathroom fittings. The product’s simple mechanism and slim profile facilitate straightforward replacement of existing flush plates or upgrading from plastic alternatives without major alterations to the concealed cistern.

Suitable for

• Residential bathrooms with concealed cistern installations
• Commercial washrooms requiring robust metal control plates
• Replacement projects where an existing flush plate needs upgrading to a metal finish
• Refurbishments that aim for a neutral nickel-mat aesthetic

When it may not be suitable

This flush plate is a direct user control and does not include electronic components or sensor functions; it may not be suitable for installations that require touchless or automatic flushing. Also, if the concealed cistern or actuator mechanism is non-standard or incompatible with mechanical push-plate interfaces, additional adapters or a different plate model may be needed.

Key specifications

• Material: metal construction with nickel-mat surface
• Design: slim push-button plate for wall-mounted operation
• Function: mechanical push activation for concealed WC cisterns
• Finish: nickel-mat for neutral, corrosion-resistant appearance
• Application: suitable for residential and commercial bathrooms

How to use

Mount the flush plate over the access opening of the concealed cistern according to the cistern manufacturer’s installation instructions. Once fitted, pressing the visible metal button actuates the concealed flush mechanism to release water from the cistern. For replacement, remove the existing plate and connect the plate’s actuator to the cistern linkage or push rod, ensuring proper alignment and secure fastening before testing the flush action.

What to consider before purchase

• Compatibility of the plate’s mechanical actuator with your concealed cistern model and linkage system
• Required cut-out dimensions and mounting method of the existing flush plate frame
• Desired finish and how nickel-mat will match other bathroom fixtures
• Whether an electronic or sensor-controlled plate is needed instead of a mechanical actuator

Usage recommendations

To ensure long service life, clean the nickel-mat surface with a soft, damp cloth and avoid abrasive cleaners or pads. During installation, follow the cistern manufacturer’s guidelines and test the actuation several times to confirm reliable operation before closing the wall access.
