Campbell 3990701 Hook Latch Kit 12000 Lb Load Limit

Product Description

The CAMPBELL 3990701 is a hook latch kit rated for a 12,000 pound work load limit, designed for lifting applications in rigging, material handling, and overhead lifting operations. The latch measures 2.375 inches in length, 1.2813 inches in width, and 0.375 inches in thickness, with a hole diameter of 0.2656 inches. It is installed by rigging professionals and millwrights who require a reliable latch replacement or retrofit on hooks already in service. The kit provides the hardware needed to restore proper latch function and maintain load-rated hook integrity.

This latch kit is suited for industrial and commercial rigging environments where hooks are subject to regular load cycles. Typical applications include crane hooks, hoist hooks, and lifting slings used in construction, manufacturing, and maintenance settings. The 12,000 pound work load limit makes it appropriate for medium-duty overhead lifting tasks where latch integrity is critical to safe operation.
