Cleat Nylon 89mm (Jam Cleat/Horn Cleat)

Hi, nothing special needed - just use s/s self tappers of s/s inox rivets through the old holes or new holes if needed.

Hi William It could be screwed to the mast or a combination of 1x rivet and 1x screw as you will not get the 'nose' of the rivet gun inside the recess of the top fixing hole Regards David

Hi William I'd go with a 4.2 x 13mm (No.8 x 1/2") Countersunk screw, drill a 3mm or 3.5mm pilot hole https://www.tridentuk.com/gb/4-2-x-13mm-countersunk-pozi-s-s-self-tappers-10-pack.html Regards David
