Quick Answer
To identify quality tarred bankline during purchase, check for the presence of a consistent, even tar application, inspect the material for signs of degradation, and verify the product's certification from a reputable organization such as the Cordage Institute. Look for banklines with a high break strength to weight ratio and a durable, water-resistant tar coating. Consider purchasing from a supplier that offers a warranty or guarantee on their products.
Material Inspection
When inspecting tarred bankline, look for materials with a consistent, even tar application. A well-done tar job will have a uniform, smooth appearance with no bare spots or unevenness. Check the material for signs of degradation, such as cracks, brittleness, or a general feeling of dryness. High-quality tarred banklines typically have a 20-30% tar content by weight and are made from durable materials like Manila or Dacron.
Testing and Certification
Verify that the tarred bankline meets specific testing standards, such as those set by the Cordage Institute. Look for products that have undergone rigorous testing for break strength, water resistance, and durability. Certified products will have a clear label or documentation indicating their compliance with industry standards. For example, a bankline with a break strength of 1,000 pounds and a water resistance rating of 24 hours or more is a good indication of quality.
Supplier Selection
Choose a supplier that offers a warranty or guarantee on their products. This ensures that you’re purchasing a high-quality tarred bankline that will perform as expected. Consider purchasing from a supplier that has a proven track record of producing reliable, long-lasting banklines. Ask about their testing and certification processes, and request documentation or labels that verify their products meet industry standards.
