Since you already have a chain hook, why not use 2 shackles attached to the hook's shackle to balance it out port&starboard, and then you might not need the chain grabber at all. Courtney Couple of reasons we don't do the two-shackles bit... The first is that there's a line through the eye which more than takes up the space allotted. It must have been put in as new, cuz it surely doesn't want to move, now (inferred age, salt, UV caused expansion somewhat). The other is that the eye isn't big enough to accommodate two shackles, in any event - or, at least, not big enough that I'd want to trust them to heavy loads such as anchor yanks. The pull of the eye is not inline with the slot of the hook...so it will always pull the link of the chain to one side. Pragmatically I don't know if this cant of the link would be significant unless one puts it to the test will some heavy and or prolonged load. I don't expect the couple-inch-off-center pull, particularly 20 or so feet out, would make any difference that could be measured. However, being somewhat of a pragmatist but more of a neatnik (elegant solutions rather than Rube Goldberg), I'm resistant to three shackles just to be able to attach two lines to a device not designed for the task. In other words, if you just don't like that little, occasional, jerk, and are not going to leave for extended periods, I can't imagine it being a problem. ...but then, I'm not a metallurgical engineer. I just play one on TV....I just haven't found any work. :{)) I wouldn't expect a problem, either - however, using this rig (one sided pull) I lost the snubber, once (just fell off, that is - it was still attached to the rode when I pulled it in. I expect the Chain Grabber, being designed to the purpose, would be far less likely to accidentally dislodge. Back to our rode/hook, however: While we didn't think (well, technically, we hadn't been exposed to the concept yet) of it in time, we surely would have wanted to use that line and hook to offset to the waves on our last night offshore during our delivery/shakedown cruise. I've forgotten the name of the technique, but it amounts to attaching a second line to the anchor chain and running it to the stern, making a bridle. Adjust the length of the anchor line to point the bow as desired. It would have allowed our entirely beam-to, very rolly anchorage, to be head-on with the wind about 60* to starboard. Otherwise, we'd want to center the anchor, and the Chain Grabber looks to do that admirably, along with sharing the momentary loads with two lines rather than just one - which might allow lighter line, too. (Our current snubber line is 5/8 or 3/4 by eye, not having measured it.)
