How is a cabinet back commonly secured to the carcass?

• A. Screwed around the perimeter.
• B. Pinned with dowels.
• C. Nailed or screwed.
• D. Held with magnets.

Answer: (C)

The back panel of a cabinet is a thin sheet that must be secured along the edges to keep the box square and stiff. The common method is to drive nails or screws through the back edges into the carcass sides, top, and bottom. This provides a quick, reliable hold that clamps the panel flat and allows for easy disassembly if needed. Dowels aren’t typically used to attach the back, magnets wouldn’t provide a secure long-term hold for a full back panel, and while screws can be used, the usual description of the method is “nailed or screwed” because both fasteners are commonly employed depending on the situation.
