Product identity
The Kinedyne 101-10312GRA grab hook is a Grade 43 carbon steel fitting rated at a 3,900 lb working load limit. It uses a clevis attachment with a 3/8 in pin and a 7/16 in inside width for chain or rigging connections. The hook opening measures 1/2 in and the overall length is 2 3/16 in.
Thermals noise power
This component has no moving parts, electronics or power draw so it produces no heat or audible noise during use. Carbon steel construction handles normal environmental temperatures without degradation. Performance depends entirely on the mechanical system it joins.
Sustained load behaviour
The hook is marked not for lifting, so it is intended for pulling or securing tasks rather than overhead hoisting. Grade 43 steel provides consistent strength under continuous tension within the 3,900 lb limit. Deformation or wear will only appear if the working load limit is exceeded.

Questions about this item
How do I install the clevis pin on this grab hook, and what step do people get wrong?
Insert the 3/8 in clevis pin through the 7/16 in clevis width and secure the retaining clip fully; the step often missed is confirming the clip is seated so the pin cannot walk out under vibration.
What maintenance or replacement will this Grade 43 carbon steel grab hook need later?
Inspect the 5/8 in material thickness and 1/2 in hook opening for wear, elongation or corrosion before each use; replace the hook if the throat width exceeds 1/2 in or the clevis pin shows bending.
What limit shows up first when this hook is used at its 3,900 lb WLL for sustained pulls?
The 3,900 lb working load limit is the governing limit; because the hook is marked not for lifting, sustained tension at WLL will reach the material yield point before any other component fails.
