Clevis Slip Hook Grade 70 (A331) is a versatile chain connection tool designed for load securement in transport trailers, tow trucks, fleet service vehicles, and roadside assistance units. The slip-style hook opening allows for easier chain movement and connection, especially when quick adjustments or releases are needed in the field.

Q: What’s the difference between a clevis slip hook and a clevis grab hook?
A: A slip hook allows the chain to move freely inside the hook, offering more flexibility in application. A grab hook, on the other hand, holds a chain link tightly in place for a fixed-length connection.
Q: Can I use this for overhead lifting?
A: No. Grade 70 slip hooks are not rated for lifting. They are designed for load securement and towing applications only.
Q: Do you offer private labeling or branded packaging?
A: Yes. We support OEM customization, including logo stamping, branded packaging, and barcode labeling.
