Scaffold Clamp Types

Tube Clamp

• Tube clamps are one of the most common type of clamps used in scaffolding. They are designed for you to fit onto the tubes. You tighten a screw or bolt via a screwdriver, wrench or socket to tighten the tube around the pipe or tube in question. Tube clamps generally are sold as part of a scaffolding set that usually includes right-angle clamps to connect vertical and horizontal sections.

Swivel Clamp

• Swivel clamps are similar to tube clamps in their function, except they are designed to attach to a pipe or tube and allow for the crossing tube to be turned at any type of angle required by the project. They are considered specialty clamps. Therefore, they generally aren't sold as part of a scaffolding set. You will need to purchase them separately, depending on the type of project on which you are working.

Coupler Clamp

• Coupler clamps are designed to fit around the ends of two different pieces of pipe where they meet to hold the pieces together. You can use them with both vertical and horizontal sections of pipes. The most common type sold simply tightens onto the pipes via a bolt. Some coupler clamps utilize a grub screw (a screw that tightens against the pipe) to hold the pipes in place.

Beam Clamp

• Beam clamps are designed to attach to the steel beams of a commercial building to hold scaffolding in place on large-scale projects. They generally are not used for small-scale scaffolding, such as those painters, carpenters and other residential workers use. They are used in pairs for projects such as high-rises.
