Scaffold Clamps


Build tube-and-clamp scaffolding and attach supports, such as railings, to frame-style structures. Also known as knuckles. These clamps fit the most common scaffold tube sizes. Made of galvanized steel, they are rust resistant and hold up in outdoor applications.
Rigid clamps create a secure 90° connection between two tubes.
Swivel clamps pivot to connect tubes at any angle.
Note: Clamps meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.

Scaffold Locking Pins


Fasten coupling pins, base plates, guardrail posts, and other components to scaffold frames. They replace missing pins on your scaffold frame to help you comply with OSHA safety requirements. Made of galvanized steel, they resist rust and hold up to outdoor use.
Pig-tail pins have a curved arm that wraps around the frame. They’re also known as gravity pins. Toggle pins have a hinged arm that flips down against the frame to lock the pin in place. They’re also known as hinge pins.
Note: Pins meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
