Sioux Chief Mfg Co. 884-ATM Abs Closet Flange 3 or 4 Inch

Product Description

The SIOUX CHIEF MFG CO. 884-ATM is an ABS closet flange designed to connect a toilet to the drain-waste-vent system at the floor level. It fits a 3-inch ABS hub connection on the outside or drops inside a 4-inch pipe, giving installers flexibility when working with either pipe size. The flange features a corrosion-proof stainless steel swivel ring that rotates for bolt alignment without needing to reposition the flange body. The knockout design removes cleanly in one piece, keeping the drain opening clear and the installation straightforward. Licensed plumbers install this fitting in new construction and remodel work.

This closet flange is suited for residential and light commercial drain installations where ABS drain-waste-vent pipe is the specified material. It is appropriate for floor-mounted toilet connections in bathrooms where either a 3-inch hub or a 4-inch inside connection is present. The stainless steel swivel ring allows the bolt slots to be oriented after the flange is set, which is especially useful in tight or awkward floor layouts.

Key Features

• Fits 3-inch ABS hub (outside) or 4-inch pipe (inside) for dual-size compatibility
• Corrosion-proof stainless steel swivel ring rotates for precise bolt alignment
• Single-piece knockout removal for a clean, unobstructed drain opening
• ABS construction resists moisture and standard drain-line chemicals
• Sold individually (unit of measure: each)

Compatibility

Designed as an OEM-style replacement or new-installation closet flange for ABS drain-waste-vent systems using 3-inch hub or 4-inch inside pipe connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the drain line is clear before setting the flange. Knock out the center plug in one piece before or after setting, depending on the installation sequence. Secure the flange to the subfloor with appropriate fasteners and verify the swivel ring bolts are properly positioned before setting the toilet.
