Wal-rich 1349604 Extra Heavy Closet Flange 4x4 Inside Caulk

Product Description

The WAL-RICH 1349604 is an extra-heavy closet flange designed for 4-inch inside-caulk connections in residential and commercial drain, waste, and vent systems. This flange provides the structural base that anchors the toilet to the floor and connects the toilet horn to the drain stack below. The extra-heavy construction adds wall thickness and durability compared to standard-duty flanges, making it a reliable choice where long service life and a solid mount are priorities. Licensed plumbers install this flange during rough-in or as a replacement when an existing flange is damaged or corroded.

This closet flange is suited for new construction and retrofit plumbing applications where a 4-inch pipe meets a 4-inch hub using a caulked joint. The inside-caulk design fits over the pipe end, allowing the flange to seat flush with or slightly above the finished floor surface. It is appropriate for use in residential bathrooms, commercial restrooms, and any application requiring a code-compliant toilet connection to a 4-inch drain line.

Key Features

• Extra-heavy construction for added durability and a solid floor mount
• 4-inch by 4-inch inside-caulk connection seats over the pipe end
• Flat flange ring accepts standard toilet bolt slots for proper toilet positioning
• Compatible with caulked-joint installation methods common in cast iron and heavy-duty DWV systems
• Weighs 4.37 pounds, indicating substantial material mass relative to standard-duty flanges

Compatibility

Designed as an OEM-style replacement or new-installation closet flange for 4-inch drain lines requiring an inside-caulk connection in residential and commercial plumbing systems.

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 remove all standing water from the drain line before beginning work. The flange top surface should be set at or slightly above the finished floor level to ensure a proper wax-ring seal when the toilet is set. This product is subject to California Proposition 65 warnings for cancer and reproductive harm.
