PETOL Flange Aligning Tools are made of steel and black oxide coated for rust protection and marked with both the bolt hole size and part number for easy identification. The tools are sold individually and in sets.
Simply find a bolt hole that is aligned enough for the tapered shaft to fit through and turn.
Turn until the bolt holes are in alignment.
If necessary, use a second tool and turn until the bolt holes are in alignment and insert flange bolts.
