The threaded adapter and rubber coupler are provided as two different installation options to connect the shower drain to the plumbing system—you only need to use one based on your setup. View image Guide

• Use the threaded adapter if extra height is needed during installation. It allows for height adjustment and provides a screw-in connection.
• Use the rubber coupler if no additional height is required and a flexible, snug connection is needed. Apply plumbing sealant if needed for extra security.

A small amount of looseness in the rubber coupler is normal and will not cause leaks. If you need detailed installation instructions, feel free to contact us for an e-copy.
