Features

Square Pattern
The block has a grid pattern on the whole block. The problem with the design is soft blocks make larger indents and won’t always meet ASTM E18-17e1 for distance between another indent and the edge. To solve this problem, use every other square.
Circle Pattern
This design will solve the problem of distance between indents to meet the standard. Some customers complained that too much space was wasted. But this is the rule of ASTM E18-17e1.
