Eastman 35389 1-1/2" Tubular Waste Arm, 15" Drain Extension

Eastman 35389 1-1/2" Waste Arm, 15" Tubular Drain Extension

The Eastman 35389 is a 1-1/2" waste arm measuring 15" in length, designed for use in tubular drain assemblies beneath sinks and lavatories. This rough-in fitting connects a P-trap or trap adapter to the drain stub-out in the wall, extending the tubular waste run to reach the wall opening when the fixture drain and wall stub-out are not perfectly aligned. Sized to 1-1/2" trade size, it is intended for standard residential and light commercial tubular waste applications where a plumber needs to bridge distance between the trap and the wall drain connection.

Key Features

• Trade Size: 1-1/2" nominal tubular size, matching common lavatory and sink drain and trap connections.
• Length: 15" overall length, giving the installer extra reach to connect a P-trap outlet to a wall drain stub-out that is offset or set back from the fixture.
• Tubular Waste Design: Configured as a straight waste arm for use in below-sink tubular drain assemblies, installed with slip-joint nuts and washers at the trap and wall connections.
• Field-Cuttable: Like other tubular waste arms, length can typically be trimmed by the installer to fit the exact rough-in distance during installation.
• Rough-In Compatibility: Designed to pair with standard 1-1/2" slip-joint P-traps, trap adapters, and wall escutcheons commonly found in tubular drain-waste installations.
