The two primary linkage options available for your multi-point latches are Rods and Cables. Each offers a different set of advantages and disadvantages.
If you're debating which is right for your application, here's a breakdown of our findings.
Rods are more common in multi-point latch applications for several reasons, but primarily because of their durability. They are generally stronger and more durable than cables. Financially, while the cost of the raw materials for rods and cables is very close, rods tend to be more economical than a complete cable system. Cable systems require more components for assembly, thus making them more complex and costly to use. Many companies will form rods on their own, which also can help to keep costs down.
