The Clamp Tab is a critical replacement part designed to maintain the airtight seal between the Air Meter base and lid, ensuring accurate readings during concrete air testing. This durable clamp screws securely into the Adjusting Rod and Latch Assembly, helping to prevent leaks and maintain consistent performance. Each Air Meter requires four Clamp Tabs for proper operation. Made from high-quality materials, it is built to withstand heavy use in demanding work environments. Keep your Gilson Concrete Air Meter functioning at its best by replacing worn or damaged Clamp Tabs promptly.
