Sioux Chief has designed two quality offset flanges the full flush and the Drop-Kick to deal with the real world problems contractors face, like a misaligned pipe or inconvenient floor joists. What makes these flanges unique is their full flow capacity. A 3 inch ball will pass through either unobstructed. This feature has enabled these flanges to pass code a first. The Full Flush has a 3 inch Schedule 40 Hub connection, which will fit into 4 inch pipe. The Drop-Kick's 3 inch spigot outlet easily connects to any fitting hub. Both are available in ABS or PVC and both are standard with a corrosion-resistant, 430 stainless steel swivel ring.
