About the MALCO DS3 LOCKING DUCT STRETCHER
The Malco Ds3 is a Locking Duct Stretcher. This locking duct stretcher pulls duct sections together and holds them in place, freeing both of your hands to align and install drive cleats. It has a durable steel frame that extends beyond the wheel edges to make it safe to push, hammer, and bend the drive cleats as necessary to complete installations.
