[SML] Sub-batten rigging suggestions....

[Bill Sapsis]

If, by Spanset you mean a synthetic roundsling*…Then yes….sort of…

You cannot choke both ends of a roundsling.  You can choke one end but the other end will require a shackle or a similar device.

My concern with using a roundsling is that it could possibly slip along the pipe.  As I’m sure you’ve seen, people, especially kids, love to grab on to legs and pull them around.  They could conceivably pull the leg hard enough to pull the sub-pipe out of the sling.  Yeah, I know it’s a bit farfetched but it could happen.

With a chain/shackle/batten clamp assembly it can’t possibly happen.  I like that a lot better.

*Spanset is a brand name that is sometimes used as the generic name for synthetic roundslings.  I’ve got nothing against Spanset but I do prefer to call rigging equipment by it’s proper name.  Makes for better accuracy.  I like accuracy.

Thanks
