Builders Best 100110282 Semi-rigid Aluminum Duct 4x8 Ft

Product Description

The BUILDERS BEST 100110282 is a semi-rigid aluminum duct section measuring 4 inches in diameter and 8 feet in length. Semi-rigid aluminum duct is used to connect dryer exhaust outlets, range hood exhausts, bath fans, and similar low-pressure ventilation equipment to wall or roof terminations. The all-aluminum construction holds its shape under normal installation bends while remaining flexible enough to route around framing obstructions. This product replaces the discontinued part number 110460. Installation is typically performed by HVAC technicians, dryer installers, or general contractors during new construction or appliance replacement.

This duct section is suited for residential and light commercial ventilation applications where a smooth, semi-rigid airflow path is preferred over flexible foil duct. Common uses include dryer exhaust runs, kitchen range hood connections, and bathroom exhaust fan terminations. Its 4-inch diameter matches the standard outlet size found on most residential dryers and bath exhaust fans, making it a direct-fit option for typical rough-in configurations.

Key Features

• Semi-rigid aluminum construction holds shape and resists crushing better than flexible foil duct
• 4-inch diameter matches standard residential dryer and bath fan exhaust outlets
• 8-foot length provides sufficient run for most single-appliance exhaust connections
• Replaces discontinued part number 110460 for continuity of supply on existing job specs
• Aluminum material resists moisture and corrosion in exhaust airstream conditions

Compatibility

Designed as an OEM-style replacement semi-rigid aluminum duct for residential ventilation applications requiring a 4-inch diameter exhaust connection. Supersedes BUILDERS BEST part number 110460.

Installation Notes

Disconnect power to the appliance before making any exhaust duct connections. Secure all joints with foil-backed duct tape or approved clamps per local mechanical code requirements — do not use sheet-metal screws on dryer exhaust duct as they can catch lint. Keep runs as short and straight as possible to maintain adequate exhaust velocity. Installations should comply with applicable IMC and manufacturer appliance clearance requirements.
