I'm looking at highfield levers for tensioning the luff wire of a new jib.
The existing one (not adjustable) has screws which will not fit through the slot on the back of the proctor mast (though it has been forced in the past and took some getting off)
What is the size of the screws (and back plate width) in the two adjustable levers on the Holt Allen spar fittings page? I think 4mm might do.
It has 3x M5 (5mm) Machine threaded cross head screws 10mm long and are 40mm apart.
The plate is 2mm thick, 14mm wide and 100mm long
I hope that helps
