What is not recommended when making alterations to engineered wood products?

When making alterations to engineered wood products, cutting or notching is not recommended due to the potential to compromise the structural integrity and performance of the material. Engineered wood products are designed and manufactured with specific load-bearing capabilities and geometric profiles. Altering these dimensions can lead to weaknesses or failures that may not be immediately apparent but could result in significant safety issues over time.

In contrast, following the manufacturer's specifications is critical because those guidelines are established based on thorough testing and engineering criteria. Similarly, making small adjustments or creating holes may be permissible under certain conditions if they are done in line with the manufacturer's recommendations and do not exceed allowable limits. Therefore, the caution against cutting or notching underscores the importance of preserving the engineered design and safety of the wood products.
