Coupling Pin for Scaffolding

Coupling pins are used to connect scaffolding frames together vertically. The pins fit on the inside of the frame and are used in conjunction with span pins, toggle pins, and clips to hold them in place.

Safeway-style (blue) scaffolding requires a 9" X 1-7/16" pin, meaning the pin is 9" long and 1-7/16" in diameter.

Waco-style (red) scaffolding requires a 7" X 1-3/8" pin.

Bil-Jax-style (yellow) scaffolding requires a 9" X 1-3/8" pin.

Because of these different lengths and diameters, pins are not interchangeable between the different scaffolding styles, so it is important to make sure you have the right pin. In addition, Safeway frames have pin holes at a 45-degree angle to the horizontal member of the frame, while Waco and Bil-Jax style frames have a pin hole at a 90-degree angle, which means that the pin holes won't line up if you stack a Safeway frame on a Waco or Bil-Jax frame. We carry pins with or without a collar depending on customer preference.
