We recently purchased a collar finish for our industrial project and it has exceeded our EXPECTATIONS... Based on our own experience this collar finish from the Climax Metal H2C series is perfect for heavy-duty industrial use. It is extremely strong and durable, providing a secure connection on our machinery. The finish also protects against rust and corrosion from harsh environments. The only downside we found is that it is slightly heavier than other collar finishes we have used before. Overall, we highly recommend this product for those in need of a high-quality collar finish for their industrial and scientific needs..
