Gunnebo GBK Clevis Safety Hooks – Secure, Durable, and Chain-Ready
The Gunnebo GBK series is a line of forged alloy clevis safety hooks designed for direct attachment to Grade 100 or Grade 80 lifting chain. These hooks feature a heavy-duty clevis connector that helps prevent mismatched chain connections, and each is equipped with the Gunnebo GripLatch—a self-closing, spring-loaded latch that locks automatically under load and offers quick visual confirmation that the hook is securely closed. The interlocking design between the latch and hook bowl adds extra protection against side impacts and accidental disengagement.
