Lambro Industries 244 Aluminum Duct Connector 4 in

Product Description

The LAMBRO INDUSTRIES 244 is a 4-inch aluminum flexible duct connector designed to join two sections of 4-inch flexible aluminum duct. This fitting provides a secure, airtight transition point between duct segments in low-pressure ventilation and exhaust systems. Constructed from aluminum, it resists corrosion and holds up in attic, crawlspace, and wall-cavity environments. HVAC technicians and installers use this connector during new construction and retrofit work where flexible duct runs require mid-run splicing or extension.

This connector is suited for residential ventilation applications including bathroom exhaust, dryer venting, and range hood exhaust runs that use 4-inch flexible aluminum duct. It is a direct-fit coupling intended for situations where two duct segments must be joined cleanly without reducing airflow diameter. The unit-of-measure is each, and it is available in a package quantity of 6.

Key Features

• 4-inch diameter fits standard flexible aluminum duct
• Aluminum construction resists moisture and corrosion
• Maintains full 4-inch bore to minimize airflow restriction
• Compact coupling design suits tight installation spaces
• Sold individually with package quantity of 6 available

Compatibility

Designed as an OEM-style replacement and installation fitting for 4-inch flexible aluminum duct systems used in residential ventilation and exhaust applications.

Installation Notes

Installation is typically performed by HVAC technicians or sheet metal installers. Power down any associated exhaust fan or air-handling equipment before beginning duct work. Secure each duct end to the connector with approved metal duct tape or screw-type clamps per local mechanical code requirements. Do not use standard cloth-backed tape, as it is not rated for duct sealing in most jurisdictions.
