Lambro Industries 3003L 4 in 90 Degree Quickfit Dryer Duct Elbow

Product Description

The LAMBRO INDUSTRIES 3003L is a 4-inch, 90-degree quick-fit elbow designed for dryer exhaust duct installations. Constructed from plastic, this elbow ships with a rubber gasket and a single screw-type clamp. It is marked "A" for straightforward identification during installation. The quick-fit design allows the elbow to connect directly to the dryer outlet without requiring a separate clamp at that joint, saving time on residential laundry exhaust runs. HVAC installers and appliance technicians working on dryer venting systems will find this fitting suitable for tight-clearance installations where a sharp 90-degree turn is required.

This elbow is used in residential dryer exhaust venting applications where a 4-inch duct must change direction by 90 degrees, typically at the transition point between the dryer and the wall duct. It is well suited for laundry rooms with limited space behind the dryer, where a compact directional fitting reduces the need for additional straight duct sections. The included rubber gasket provides a secure, air-tight seal at the connection point.

Installation Notes

Installation is typically performed by an HVAC technician or qualified appliance installer. Disconnect and unplug the dryer from its power source before servicing any exhaust duct connections. Ensure all duct joints are fully seated and sealed to prevent lint or exhaust gas from accumulating in the laundry space. Follow local mechanical codes and the dryer manufacturer guidelines regarding maximum duct length and allowable number of elbows in the exhaust run.
