* Other formulations may exhibit similar performance characteristics, but must meet or exceed the performance levels for the

systems specified to be considered equal.

** Blocking may be specified in certain hardware applications where the specifier deems the frequency and severity of use

so dictates. Blocking is a material used for improved screwholding at hardware attachment points (not required in core types

such as SCL or staved lumber).
