Lambro 435 Aluminum Adjustable Elbow 8 in 22.5-90 Deg

Product Description

The LAMBRO 435 is an 8-inch aluminum adjustable elbow designed for duct system installations where a fixed-angle fitting will not work. The elbow adjusts from 22.5 degrees to 90 degrees, allowing the installer to dial in the exact bend needed without cutting or fabricating custom ductwork. One end arrives crimped for direct insertion into standard duct fittings. Constructed from aluminum, it offers light weight and corrosion resistance suitable for residential and light commercial ventilation applications. HVAC technicians and sheet metal installers will find it useful in tight or irregular spaces where a rigid elbow would be impractical.

This elbow is suited for exhaust and supply duct runs in residential HVAC systems, bathroom exhaust, dryer venting, and range hood connections where an 8-inch round duct diameter is called for. The adjustable design is particularly valuable during rough-in when duct routing must navigate framing, beams, or other obstructions. It performs well in both new construction and replacement installations.

Key Features

• Adjustable angle range from 22.5 degrees to 90 degrees for flexible duct routing
• 8-inch diameter fits standard round duct connections
• One crimped end for direct insertion into adjoining duct sections
• Aluminum construction for lightweight handling and corrosion resistance
• Eliminates the need for custom fabrication in irregular duct paths

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 8-inch round aluminum duct systems in residential and light commercial ventilation applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers following local mechanical codes and SMACNA duct construction standards. Secure all connections with sheet metal screws and seal with listed foil tape or mastic to meet code requirements for airtight duct systems. Power down or de-energize any associated air handling equipment before working on connected ductwork. Do not stretch or over-bend the elbow beyond its rated 90-degree maximum adjustment.
