Practical Notes
Ensure frames are checked for squareness by measuring diagonals before fixing into the masonry and glazing.
Apply at least one coat of anti-corrosive primer (such as red oxide zinc chromate) before site installation to prevent rusting.
Fixing lugs must be aligned properly with masonry joints to ensure rigid anchoring without requiring excessive breaking of the wall.
