TWN 1838
Swivel Self-Locking Hooks

The Grade 100 swivel self-locking hooks TWN 1838 are used to assemble chain- and wire rope- slings and are often used in the construction industry.

The swivel with ball-bearing allows the operator to swivel the load under load. When the hooks are under load, they lock automatically. They may only be reopened manually when the hooks are not under load anymore.

The self-locking hooks comply with the ASTM A952/A952M, DIN EN 1677-3 under consideration of Grade 100 working load limits.
