The two upright lines represent the two saints John. Masonic Lodges in North America are also referred to as St Johns lodges, and these two saints are representing their core values. John the Baptist represents leniency and compassion, while John the Evangelist stands for strictness and severity. They remind the mason never to be too lenient or too strict, but instead to lead a moderate and centered life.
