The STANLEY lxht14703 is a duct knife designed for cutting sheet metal ductwork and related HVAC materials. Built for trade use, it delivers the control and edge retention needed for clean cuts on flexible duct, rigid sheet metal, and duct board. HVAC technicians and sheet metal workers reach for a dedicated duct knife when utility blades lack the profile or rigidity required for consistent duct fabrication and field modification. This tool is manufactured by Stanley Black and Decker and ships as a single unit.
The lxht14703 is suited to residential and light commercial HVAC work where field cutting of duct sections, takeoffs, or insulated duct board is part of the daily workflow. It fits naturally into a sheet metal tech's pouch alongside tin snips and scribes. Installers working new construction rough-ins and service techs handling duct repairs and modifications are the primary users of this tool.
Designed as a general-purpose duct knife for use with flexible duct, rigid sheet metal duct, and duct board materials common in residential and commercial HVAC installations.
Duct knives are used by licensed HVAC technicians and sheet metal workers. Always shut down and de-energize the HVAC system before performing any duct cutting or modification in a live system. Use appropriate cut-resistant gloves when working with sheet metal duct edges, as burrs and cut edges present a laceration hazard. Dispose of sheet metal offcuts safely to prevent jobsite injuries.
