Questions about this item

How do I pick between the 4 x 3 inch hub and other flange sizes?

This model is a 4 x 3 inch hub closet flange with stop; choose it when your drain pipe matches those dimensions and you need a built-in stop for the toilet horn.

What does the -40 to 180 degree F temperature range mean for daily use?

The ABS body handles continuous service from -40 °F to 180 °F, so it remains rigid in freezing crawl spaces and won't soften under hot waste water.

Which standards govern the hub connection and material quality?

The flange meets ASTM D2665 for dimensions and performance, ASTM D3311 for patterns and laying length, and the ABS material satisfies ASTM D3965 cell class 32222.
