      The Coast Guard has recently discovered problems with corroded snap hook spring clips on four models of Type I Coast Guard Approved Lifejackets manufactured by Cal-June (a.k.a. Jim Buoy). Each uses a metal snap hook to D-ring assembly to close the jackets and the problem lies with the spring clip, a thin piece of metal attached to the base of the hook that keeps it from disengaging once connected to the D-ring.

      The spring clips for the affected models were made from the wrong material and as such corrode and fall off, in some cases after less than a year of service. Once this happens, the snap hooks can easily become disconnected from the D-ring, allowing the life jacket to open.

       Cal-June has acknowledged the problem and is committed to replacing the defective hooks free of charge to lifejacket owners. According to the company, a total of 5,371 lifejackets having the defective snap hooks were manufactured and sold between October 1, 2002 and March 15, 2004. If your lifejacket falls within the lot numbers listed below, contact Cal-June Inc. at (818) 761-3516 or e-mail them at to receive replacement snap hooks (there is no need to return the lifejacket itself). The company will need the model number, lot number, quantity of lifejackets requiring replacements and a shipping address. Instructions for replacing the snap hooks can be viewed at

      The entire snap hook (including the clip) should be of non-magnetic materials such as bronze or stainless steel. A simple way to verify this is by touching them with a small magnet if it is attracted to or attaches to the clip, the snap hook assembly must be replaced.
