G Pin Scaffolding G Pin / Joint Pin

A G Pin, also called a Joint Pin or Gravity Pin, is a scaffolding accessory used to connect two scaffolding pipes or props securely. It is shaped like the letter “G”, allowing it to easily lock into place and hold the components firmly during construction.
NOVSA manufactures G Pins using high-strength steel with precise dimensions, ensuring durability, safety, and easy installation at construction sites.
