Copperfit 1A1902 Adjustable Closet Flange 4 Inch Abs Dwv

Product Description

The COPPERFIT 1A1902 is a 4-inch hub adjustable closet flange designed for ABS DWV (drain, waste, and vent) piping systems. It includes an adjusting ring that allows the flange collar to be raised or lowered to meet finished floor height, eliminating the need to cut and reset the flange when tile or other flooring raises the surface level. Licensed plumbers install this fitting during rough-in or finish work on residential toilet connections. The ABS construction keeps the part lightweight and resistant to corrosion in wet drain environments.

This closet flange is used in residential plumbing installations where ABS drain piping is present. It is suited for new construction and remodel work where the finished floor height may differ from the rough-in elevation. The hub connection solvent-welds directly onto a 4-inch ABS pipe stub-out, and the adjusting ring sets the flange face flush with the finished floor surface before the toilet is set. This fitting is appropriate for single-family homes and light commercial applications using ABS DWV systems.

Key Features

• Adjusting ring allows flange height to be set to match finished floor elevation
• 4-inch hub end solvent-welds to standard ABS DWV pipe
• ABS construction resists corrosion and moisture in drain service
• Lightweight design simplifies handling during rough-in and finish installation
• Compatible with standard toilet bolt patterns for straightforward toilet setting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch ABS DWV drain systems in residential and light commercial toilet rough-in applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC or applicable regional code. Shut off the water supply and ensure the drain line is clear before beginning work. Use approved ABS solvent cement when making the hub connection, and allow full cure time before setting the toilet. Do not overtighten closet bolts, as this can crack the flange collar.
