5" × 8" × 16"
Special order5" × 8" × 16" Brick
The longest face in the range, at a five-inch section. It covers ground as fast as the 4×8×16 but carries more section, which tells on tall internal walls and infill panels that would otherwise need a six-inch bed. Cast to order rather than held in the yard.
Detail and specification

Photography pending. This image shows a comparable size from the same mix.
This size is made to order. We schedule the cast once the order is placed and confirm a ready-for-delivery date at that point, so it is not held in the yard and cannot be collected off the shelf. Order ahead of when you need it.
