Security is taken to the next level with the reinforced long hardened steel shackle. Specially heat-treated to resist cutting, sawing, and prying, this high-strength shackle creates a formidable barrier against tampering and break-ins. The extended length of the shackle also provides extra clearance, making it perfect for larger fixtures like thick storage unit doors, heavy toolboxes, and outdoor gates that standard short-shackle locks can’t accommodate.
