FAQs
Is this a complete flushing kit?
No — this listing is for the button only (large face).
Will it fit smaller lid holes?
It is designed for lids around 49 mm. Measure your aperture to confirm suitability.
Why choose the large face version?
The larger face gives a broader push area and a bold look — often preferred in higher-use or accessible (Doc M-style) setups.
