Key Benefits
What G80 Clevis Forest Hook Gives You
- Narrow throat opening prevents chain from slipping out during dynamic loading in logging and reeving operations
- Drop-forged alloy steel body with quenched and tempered heat treatment ensures high tensile strength and impact resistance
- No safety latch allows easy chain insertion and removal while maintaining secure engagement under load
- Powder coated or painted surface finish resists corrosion in outdoor and harsh field environments
- Grade 80 material provides a 4:1 design factor with minimum breaking load four times the safe working load
- Compact clevis design reduces bulk and weight compared to larger shackles, ideal for mobile rigging setups
- Standardized dimensions and tonnage marking allow quick verification of compatibility with chain and load
Application Scenarios
Where G80 Clevis Forest Hook Is Used
- Logging operations where chains are reeved through tree anchors or skidding systems under high tension
- Forestry cable logging setups using chain and hook systems to move logs across uneven terrain
- Mobile rigging on logging trucks or skidders where space and weight are limited
- Material handling in remote or off-grid construction sites with chain-based lifting and pulling
- Reeving applications where a chain must be quickly attached and detached from a load point
Who It Is For
Buyers This Product Is Built For
- Forestry and logging contractors specifying chain and hook systems for skidding and yarding
- Rigging suppliers sourcing Grade 80 hooks for use in logging and industrial reeving
- Equipment manufacturers building mobile logging or material handling kits
- Contractors in remote areas needing durable, low-maintenance rigging hardware for chain systems

Problems It Solves
Problems This Product Removes
- Chain slipping out of a hook during high-load logging or reeving due to wide throat or loose latch
- Using a hook with insufficient strength for Grade 80 chain, risking failure under load
- Lack of compatibility between hook size and chain diameter leading to misalignment and wear
- Corrosion damage in outdoor logging environments due to untreated steel surfaces
- Need to source hooks and chains from separate suppliers, increasing procurement complexity
- Inconsistent marking or traceability making it hard to verify working load limits in the field

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Safety latch hook | The clevis forest hook allows faster chain insertion and removal but lacks a latch, so it must be used where accidental dislodgement is unlikely |
| Screw pin shackle | The clevis design is simpler and more robust for chain use, but a screw pin shackle offers easier field adjustment and inspection |
| Standard hook with wide throat | The narrow throat prevents chain slippage under load but requires precise alignment with chain diameter |
| Grade 70 hook | Grade 80 offers higher strength and breaking load for the same size, but is not suitable for all chain types without verification |
Use Guide
How To Use And Inspect G80 Clevis Forest Hook
- Verify the hook size and chain diameter are compatible before attaching to a load
- Do not exceed the stamped working load limit under any circumstances
- Ensure the chain is fully inserted through the throat and seated properly before loading
- Inspect the hook for deformation, cracks, or wear before each use
- Keep the hook aligned with the chain direction to avoid side loading
- Retire the hook if the throat opening shows distortion, the marking is illegible, or the finish is damaged
