Lambro Industries 2310 Aluminum Adjustable Duct Elbow 4in

Product Description

The LAMBRO INDUSTRIES 2310 is an aluminum adjustable duct elbow designed for 4-inch duct systems. It allows technicians to change airflow direction within ventilation runs where fixed fittings would not accommodate the required angle. The adjustable design reduces the need for multiple fixed-angle fittings on the job, making it a practical choice for HVAC installers and sheet metal mechanics working on residential and light commercial duct layouts. The aluminum construction keeps the fitting lightweight while providing adequate rigidity for standard dryer vent and exhaust duct applications.

This elbow is suited for use in 4-inch round duct systems, including dryer exhaust vents, bathroom exhaust fans, and general HVAC ventilation runs. Its adjustable pivot lets installers fine-tune the transition angle to match actual field conditions, which is especially useful in tight wall cavities, crawl spaces, and attic runs where rigid pre-bent elbows create fitment problems. HVAC technicians and ventilation contractors are the primary installers.

Key Features

• Adjustable angle accommodates varying field duct routing conditions
• Aluminum construction — lightweight and resistant to moisture in exhaust applications
• Fits 4-inch round duct diameter
• Reduces need for multiple fixed-angle fittings on a single run
• Sold individually (unit of measure: EA)

Compatibility

Designed as an OEM-style replacement and new-installation fitting for standard 4-inch round residential and light commercial ventilation duct systems.

Installation Notes

Installation is typically performed by HVAC technicians or ventilation contractors. Power down any connected exhaust fan or air-handling equipment before beginning duct work. Secure all duct connections with appropriate foil tape or approved clamps per local mechanical code requirements. Avoid using sheet metal screws on dryer exhaust duct interiors, as screws can catch lint and create a fire hazard.
