The Gunnebo UKN Weld-On Hook is a Grade 100 hook designed for permanent welding onto steel structures, equipment, and custom rigging hardware. Once welded in place, the UKN provides a fixed lifting or connection point with a spring-loaded safety latch to prevent accidental load release.
Key Features
- Grade 100 forged alloy steel construction
- Weld-on base for permanent attachment to steel surfaces
- Spring-loaded safety latch prevents accidental disengagement
- Generous throat opening for versatile sling and hardware connections
- Proof tested and traceable
Common Applications
- Permanent lifting points on custom fabrications and equipment
- Fixed hook points on containers, frames, and structural assemblies
- Material handling fixtures and production tooling
- Any application requiring a permanently attached Grade 100 hook
Why Gunnebo?
The UKN provides a permanent Grade 100 hook connection without the complexity of bolt-on mounting. Ideal for custom fabrications where welding is the preferred attachment method and a rated lifting point is required.
