The Grade 80 Alloy Steel UKN Weld-on Hook introduced by Gunnebo Lifting Company in 1975 was originally designed for excavator and backhoe use. These Grade 80 alloy steel hooks provide heavy-duty connecting points to any metal surface that is compatible to the load requirement and recommended welding criteria. This is a ready-to-use cargo control device that can also be used as a lifting point. If this hook is more than you need, then you can check out our lighter-duty Weldable Grab Hooks, which are made from Grade 30 steel and are popular with farmers, ranchers and land owners. We also offer RDUKN Replacement Latch Kits for these hooks. Since these hooks are used primarily on excavator buckets, they are prone to take a lot of abuse, and latch kits should be replaced as soon as they become inoperable.
