Product Description

Product Overview

Manual Strapping Tool 13-19mm 0.38-0.8mm

The SG191 Manual Strapping Tool revolutionizes heavy-duty bundling with its sealless, powerless design, engineered to secure industrial loads without cords, consumables, or compromises. Compatible with steel, aluminum, and copper straps ranging from 12.7–19 mm in width and 0.38–0.8 mm in thickness, it leverages a patented "yin-yang" interlock system to mechanically fuse strap ends, achieving 70–85% joint strength relative to the strap's tensile integrity—eliminating seal consumables and reducing operational costs by approximately 10%. Generating up to 50 kg of tension force (or 6,000 N in premium models), this tool effortlessly immobilizes heavy loads such as steel coils, aluminum ingots, lumber stacks, and construction materials, ensuring stability during transit or storage.
