The base course of any wall or fence project needs to be full-size blocks. The above block counts are for the pattern sections only and do not include the additional blocks needed for the base course. For each 10-ft. section of wall or fence you will need seven (7) full-size AB Dover or AB Classic blocks for wall sections, or AB Fence Panel blocks for AB Fence sections. If using AB Caps on the project, you will also need seven (7) AB Caps for each 10-ft. section of wall or panel length.
