A Precision Plumbing Upgrade: The Metric Flush Fit Flange with Knockout for Cleaner, Faster Installs
May 27, 2026Plastic Oddities Team

When installing water closets, precise flange alignment and rigid floor connections make the difference between a quick trim-out and an expensive call-back.
### Advantages of the Flush Fit Flange with Knockout:
- **Flush Mount Profile**: Sits flush with subflooring for solid fixture placement.
- **Integrated Knockout Cap**: Built-in test cap allows rough-in pressure testing; knocks out cleanly with one hammer tap.
- **Solvent Weld Fit**: Fits inside schedule 40 DWV pipe cleanly.
