Outdoor enthusiasts and DIYers, these DELSWIN carabiner clips are seriously heavy-duty! With a working load limit of 855 pounds (388kg), these aren't your cheap keychain carabiners - they're built for real tasks. Each carabiner measures 3 inches long with 5/16 inch thickness, made from electrophoretic coated carbon steel that resists chipping and rust. The improved spring mechanism allows smooth one-handed operation, and they've been tested through thousands of open-close cycles to ensure reliability. The glossy black finish looks professional and holds up well to outdoor elements. These D-shaped spring hooks are perfect for so many applications - use them for hammocks, dog leashes, camping gear, gym equipment, keychains, backpack attachments, securing loads, or organizing tools. The spring-loaded gate locks securely to prevent accidental opening. IMPORTANT NOTE: While these are heavy-duty, they're NOT for climbing or life-support applications - they're for general purpose use where safety isn't critical. The 6-pack means you'll have plenty for multiple projects or to keep in different locations. Whether you're setting up a backyard hammock, organizing your garage, taking your dog for a walk, or need reliable clips for outdoor adventures, these carabiners handle the job with ease. The quality is noticeably better than typical hardware store carabiners, and the 855-pound rating gives you peace of mind for heavy loads. For the price, getting six of these quality clips is an absolute steal!
