Note: The minimum cover for vulcanized splice is 1/8 in. (3.2mm). The recommended is maximum top to bottom cover ratio for one ply is 2:1 (i.e., is 1/4 in. x 1/8 in. or 4.5mm x 2.25mm)
and for two ply is 3:1 (i.e., is 3/8 in. x 1/8 in. or 9mm x 3mm). Above tables are based on top cover gauge equal or greater than the bottom (pulley) cover gauge.
