Armitage Shanks Septa Pro M1 Mechanical Metal Dual Flush Plate - Chrome - S0858AA
Armitage Shanks Septa Pro M1 Metal Dual Flush Plate in Chrome
An anti-vandal metal dual flush plate built for commercial washrooms. Zinc die cast rather than plastic, chromium-plated to a glossy chrome finish and rated by Armitage Shanks as anti-vandal.
The Septa Pro M1 is the plate you specify when a washroom takes a beating. It measures 243mm wide by 163mm high, projects 17mm and weighs 1.02kg, which is close to three times a comparable plastic plate. Both buttons still press at under 20N, the flush is mechanically operated in the event of a power failure, and the chrome carries a SmartShine surface that wipes clean without a cleaner.
Is the Septa Pro M1 the right flush plate for your washroom?
Two questions settle it: how hard is this washroom used and what frame is behind the wall.
Judge the traffic and the abuse
This is a commercial plate. Armitage Shanks specify it for these settings.
- Education, healthcare, hotel, leisure and office
- Anti-vandal rated for public washrooms

Confirm the frame and the rods
It fits ProSys mechanical actuation frames and cisterns. The mounting frame and connector rods are supplied but the activation rods are not, so check what your cistern already has.
Metal against plastic, side by side
Septa Pro M1 Metal · anti-vandal · 1.02kg · 17mm projection (this product)
Oleas M3 ABS plastic · matt black · 0.36kg · 8.5mm · view the M3
Oleas M2 ABS plastic · brushed chrome · 0.36kg · 8.5mm · view the M2
All three are mechanical, so all three flush normally in a power cut. Only the Septa Pro is anti-vandal rated.

Zinc die cast metal, not plastic
The plate is metal rather than moulded plastic, which is why it weighs 1.02kg against roughly a third of that for a plastic plate. It is chromium-plated to a glossy chrome finish and carries a SmartShine surface that keeps marks and water spotting easier to wipe away.
Anti-vandal rated for public washrooms
Armitage Shanks list the S0858AA as anti-vandal. That is the reason to specify it over a domestic plate in a school, a leisure centre or any washroom that sees heavy or careless use. Both buttons still press at under 20N so it stays easy for everyone to operate.

Two flush volumes with no electronics to fail
A purely mechanical dual flush plate. The buttons are spring-loaded and act directly on the cistern valve, so the flush is mechanically operated in the event of a power failure. Servicing afterwards is tool-free.
