If you have older HF stands, this recall and safety issue doesn't really apply to you. I have several sets of the 1990's orange/yellow HF stands, and the pawls engage fully. I also have a set of old 1960s US made Atlas stands and the pawls are an exact match to the HF - in fact they're interchangeable.
I've noticed that once HF changed suppliers and moved from their decades old orange/yellow painted shop equipment line to the gray painted line, the quality suffered tremendously; especially in their hydraulic equipment lines. There is no comparison between an older orange/yellow engine hoist or 20 ton press to their newer gray colored replacements. The changeover happened about 10 years ago when HF dropped a lot of their heavy machinery and shop equipment suppliers.
