Z Counterform Sink Form

The Z Counterform Sink Form is specially designed to create clean, precise openings for undermount sinks in cast-in-place concrete countertops. Measuring 8 ft. long by 3-1/4" tall, this self-adhering flexible form easily conforms to most sink shapes, ensuring a professional finish every time. Ideal for both single- and double-bowl sinks, it can be notched with a utility knife to bridge dividers, maintaining a smooth, continuous edge. Engineered for compatibility with the full Z Counterform System, this sink form simplifies forming and finishing sink cutouts, saving time and ensuring consistent results in every pour.
