The jaw straddles a tang or eye and pins through with a bolt, so the joint can pivot instead of being locked solid. That flex is what lets a bimini fold and a frame absorb movement rather than cracking a weld when the boat works in a chop.
Only if you stop it turning. A jaw slide clamps by friction on the tube, and vibration on the trailer will walk it along over a season. Check it after the first few trips and renip it, or drill and pin the tube if it keeps moving.
Off the tube diameter, and no size is listed for this fitting, so measure before you commit. Take the outside diameter with a vernier or a tape pulled round the tube and divided out, because guessing between neighbouring rail sizes is how you end up with a fitting that will not close.
