Position Assignment

• T — Top/Head rail: first Width dimension in EVA fabrication row
• B — Bottom/Sill rail: second Width dimension (receives water drainage holes)
• L — Left Jamb / Hinge Stile: determined from "View From Inside" diagram
• R — Right Jamb / Lock Stile: opposite side, carries handle routing

Water Drainage

• Y on B piece of outer frame only — N on all other pieces

Fastener Holes

• Y on T, B, L and R of outer frame — N on all sash pieces

Handle Routing

• R stile of sash → handle type from Technicals table (CASEMENT HANDLE / SLIDING HANDLE)
• L stile of sash → hinge operation (CONCEALED HINGE / 3D HINGE / FRICTION STAY)
• Frame pieces and sash T/B → blank

Components

• Simple units: OUTER_FRAME / SASH_1
• Combination (Top Fixed): OF1 (fixed section) + OF2 (operable section) + SASH_1 / SASH_2
• Sliding with mesh: SASH_1 / SASH_2 / MESH

Reinforcement Pairing

• Matched by dimension from Reinforcement section — thickness from item code suffix: -1.0 / -1.2 / -2.0
