Product Notes

To calculate pieces required for standard units, multiply the length of wall, in feet, by 1.5 for the number of pieces per row. Then multiply number of rows for amount of standard pieces. To calculate coping pieces required, multiply the length of wall, in feet, by 1.6 for amount of coping pieces required. 2 out of 12 coping pieces is an end piece. Each bundle of 60 standard has 60 tapered units (30 left and 30 right). Use all lefts and rights on alternate rows. Minimum inside diameter of 192″. For coping pieces, half the bundle will have a radius on one side, and the other half will have the opposite radius. A $25.00 returnable pallet fee will be charged to any bundle of RomanPisa.
