• Use the exact product name and manufacturer identifier on the submittal; do not substitute a similar family name.
• Attach the current product data sheet and the applicable installation, safety, approval and warranty documents.
• Record selected options such as size, thickness, profile, color, finish, reinforcement and attachment method.
