Manta Foil Plate to Tuttle Adapter

[RATbeachrider]

My buddy has the Lift Foil 200 Classic and he bought the pictured plate to tuttle box adapter for use in his Kalama Board which has the tuttle box.  He sent me the picture and it does not look right with the set screw.  I think the set screw is to prevent the bolt from backing out.  Inputs appreciated.  Thanks.

Looks to me like the set screw is just stopping the barrel nut from sliding left or right out of its hole. It cant be to stop the tuttle bolt from backing out as it would be innaccesable once in the board.
Looks like a nicely machined fitting though, I hope all goes well.

Thanks Kiwi!  I just looked at it and yes the set screw is abutting the barrel nut.  This adapter plate is pretty sweet.
