Lambro Industries 229 Aluminum Duct Pipe 4 in X 2 Ft

Product Description

The LAMBRO INDUSTRIES 229 is a rigid aluminum duct pipe section measuring 4 inches in diameter and 2 feet in length. Designed for use in residential and light commercial ventilation systems, this pipe section connects ductwork runs in dryer exhaust, bathroom exhaust, range hood, and HVAC supply or return applications. Aluminum construction keeps the pipe lightweight and resistant to corrosion. HVAC technicians, sheet metal contractors, and plumbers use this type of pipe section when assembling or extending duct systems that require a durable, rigid metallic connection.

This duct pipe section is suited for installations where a short, rigid aluminum segment is needed to complete or repair a ductwork run. Typical applications include dryer venting, bathroom and kitchen exhaust routing, and low-pressure ventilation trunk lines in residential construction. The 4-inch diameter is a common size across many exhaust and ventilation configurations. Each unit is sold individually and packages are available in quantities of 25, making it practical for both single-repair jobs and larger installation projects.

Key Features

• 4-inch diameter matches common exhaust and ventilation fitting sizes
• 2-foot length provides a manageable rigid section for short duct runs and transitions
• Aluminum construction resists corrosion and keeps weight low
• Rigid pipe form holds shape under normal ventilation airflow and pressure
• Available in case quantity of 25 units for multi-unit or new-construction jobs

Compatibility

Designed as an OEM-style replacement and standard-fit component for 4-inch diameter rigid aluminum ductwork systems used in residential and light commercial ventilation applications.

Installation Notes

Installation is typically performed by HVAC technicians or sheet metal contractors. Power down or disconnect any mechanical ventilation equipment before cutting into or modifying an existing duct run. Secure all joints with approved metallic foil tape or sheet metal screws in accordance with local mechanical codes and applicable IMC or SMACNA guidelines. Do not use this rigid pipe section as a flexible connector or substitute for approved flexible duct where movement or vibration isolation is required.
