Attachment clips for flush metal base, serving as grounds for plaster, must be which of the following?

• A. Be of manufacturer design
• B. Have adjustable teeth
• C. Be painted white
• D. Be reusable

Answer: (A)

The main idea is that clipping hardware used as a ground for plaster must be a product designed by the manufacturer for that exact flush metal base. When a clip is specifically engineered for a base, it’s tested to fit the base’s profile, spacing, and bite, ensuring a secure mechanical bond between the metal base and the plaster system. This compatibility is essential for reliable plaster keys, proper load transfer, and long-term durability of the plaster wrap around the base. Using a clip that isn’t the original manufacturer design can result in poor fit, inadequate bonding, or failure of the plaster system, even if other features like color or reuse seem convenient. The other options don’t address the core requirement of guaranteed fit and performance: adjustable teeth, white paint, or reusability do not ensure the clip will perform correctly with that specific base and plaster setup.
