What are the available lengths for 150mm lengths?

• A. 4 m or 5 m
• B. 6 m or 8 m
• C. 3 m or 4 m
• D. 5 m or 6 m

Answer: (A)

For 150 mm components, stock is typically offered in 4 meters and 5 meters. This range hits a practical balance: it's long enough to span common install distances without too many joints, yet light enough to handle and transport easily. Longer lengths like 6 or 8 meters become cumbersome to move on site and may require special handling or orders, while shorter lengths such as 3 meters would mean more joints, increasing installation time and potential leakage points. So 4 meters and 5 meters are the standard available lengths.
