Unlike standard stretchers that\nrequire constant pressure, the DS3 locks onto the duct flanges, holding the\nsections together for you. This frees both of your hands to properly seat the\ndrive cleat, ensuring an airtight connection every time without the need for a\nsecond person. Speed and Versatility in the Field Time is money on the\njobsite, and the DS3 is built for speed. There is no need to fumble with wheel\nadjustments; the movable cam system allows you to lock onto the duct from\neither side of the connection instantly. Whether you are dealing with pristine\nnew ductwork or struggling with misshapen flanges in a remodel, the increased\nwheel clearance makes capturing and pulling the metal effortless. Built Tough\nto Work. Perform. Outlast. Malco knows that HVAC tools need to take a beating.\nThe DS3 features a rugged, all-steel frame designed to withstand the force of\na hammer. Because the frame extends beyond the wheels, you can use the tool as\na sturdy surface to bend and seat drive cleats as necessary. This \"shop-floor\"\ndurability is packed into a portable hand tool that fits perfectly in your\npouch. Safety and Serviceability The offset handle isn't just for comfort—it’s\na safety feature that keeps your knuckles away from sharp, jagged metal edges.\nTo ensure your investment lasts for years, the DS3 is designed for long-term\nserviceability with replaceable wheels (DS1C, sold separately). From the\nreinforced steel body to the user-friendly locking mechanism, the DS3 is the\nprofessional standard for ductwork assembly.
