1-3/8″ Diameter Coupling Pin | Solid Aluminum

1-3/8″ Solid Aluminum Coupling Pin (CP9-13/8-SAA)

The 1-3/8″ Solid Aluminum Coupling Pin is a high-strength connector specifically engineered to vertically join scaffold frames or pipe sections. Because it is machined from solid aluminum, this pin provides an exceptional strength-to-weight ratio while remaining completely resistant to rust and corrosion. This makes it an ideal choice for contractors working in coastal areas or high-moisture environments.

We designed this pin with a precision center collar to ensure even weight distribution across scaffold standards. Additionally, it features integrated holes compatible with standard safety rivets or toggle pins to prevent accidental frame separation. Whether you are expanding a rolling tower or setting up a stationary scaffold, the CP9-13/8-SAA ensures a maintenance-free and reliable connection.
