Telescopic transom internal rod !
That's to slide back trannies say 2 inside boards to 1 not a bad tool as it goes but u need 2 one each end of the fleet
Don't you need a couple in the middle if its a 13' board?
Isn't it a version of that safelink board retainer but with a built in trip hazard?
Is that an Ikea instruction manual?
Sorry lads I looked again there not what I use lol.... never seen these before!!!!!
Head over to Ardmore and you'll find they call these "Harry Potters "
