A kind of molding installed on the vertical wall used to accept aluminum soffit panels is which channel?

• A. J channel
• B. Z support
• C. F channel
• D. S channel

Answer: (C)

When installing aluminum soffit panels, you need a receiving edge along the wall so the panel edges can slide in and be secured. This is provided by the F-channel. It creates a shallow channel with a base fastened to the wall and lips on the sides to hold the soffit edge, giving a clean, secure appearance at the wall line. J-channel finishes outer edges where siding ends or wraps around openings, not the receiving channel for soffit panels. Z-channel and S-channel are different profiles used in other siding or paneling applications, but they don’t serve as the dedicated soffit-receiving channel.
