ZieglerWorld sells American Brand and ZieglerWorld Brand Table Shuffleboard Pucks. They come in two different sizes -- medium and large.
Medium pucks are 1 7/8 at the cap and 2 1/8 at the middle and used on tables 12 feet or shorter where the table width is 16 inches.
Large pucks are 2 1/8 at the cap and 2 5/16 at the middle and used on tables 14 feet or longer where the table width is 20 inches.
Both the American Brand and ZieglerWorld Brand table shuffleboard pucks have screw on caps so if you break a cap - you only need to replace the cap not the entire puck. American Brand pucks come in Red/Blue while ZieglerWorld Brand pucks come in 21 different colors.
