The patented Vic-Lok shackle’s design improves on other shackles’ safety, the company says, by being permanently attached until it is cut off and eliminating the possibility that an operator may use an incorrect shackle.

IntegriCert is a portable load testing company for oilfield services equipment, transit cargo containers, skid units, wire rope slings and connex shipping containers.

The company says its shackle has a five-to-one load safety factor, with certified load ranges from 3.5t to 13t, and is available in 1/2 in, 5/8 in, 3/4 in, 7/8in and 1in sizes.

“The Vic-Lok is one of the first shackles designed to address the most common shackle-related safety concerns,” said Vic Segura, president of IntegriCert. “As shackles are often stored separately from the slings, we designed this permanently captivated shackle to eliminate the dangerous risk of shackles that are too small for the load, or different sizes on the same sling, leading to an unbalanced lift.”

Meeting the requirements of Federal Specification RR C-27-1-D, Type 4-B, Grade A, the shackle also meets and exceeds ASME B30.26 requirements. All shackles are provided with ABS and DNV “pull to destruction” test documents.
