C & S Connector duct

Slip and Drive Cleats system is generally used for low-end, less-critical applications. Traditionally, only the Drive cleats (“C”) which are positioning cleats were used for all four sides. This was giving a poor joint. The Slip cleats (“S” / “Standing S”) on the alternate opposite sides provide the moderate rigidity to the joint. While installing, Drive cleats are always fitted on the shorter sides and Slip cleats on the longer sides.
