COUPLING PIN 9inX1-1/4in W/1in Collar

Coupling Pin 9″ × 1-1/4″ w/ 1″ Collar

This 9 inch coupling pin connects scaffold frames and keeps each section aligned. You insert the pin into the top of the frame, slide the next frame over it, and lock both pieces together. Because the pin holds the frames straight, it helps you build a solid and level scaffold structure.

The pin measures 9 inches long and 1-1/4 inches in diameter. It also includes a 1 inch collar for secure positioning. The collar stops the pin at the correct depth, which keeps the frames from shifting. This improves stability and makes setup faster.

Each pin is made from high-tensile steel. The material resists bending and works well on busy job sites. The galvanized finish also helps protect the pin from rust, which increases its life span. You can use the pin on most standard scaffolding systems that accept 1-1/4 inch diameter connections.

Contractors use coupling pins to stack frames safely and maintain proper alignment. When the frames stay level, platforms sit flat and the scaffold feels more stable. This reduces adjustment time and helps crews work with confidence. The pin also fits easily through pin holes and removes quickly when you take down the scaffold.
