Sash clamps are commonly used for large projects like doors, cabinets, sash windows, and tabletops.

Generally, more than one clamp is used at a time for ensuring a strong grip on the projects. These sash clamps have a long flat bar which is very heavy and a fixed jaw is attached to it.

You can adjust this screw with a fixed jaw. Additionally, sash clamps have a sliding jaw that can be moved along the length of the clamp.

These types of clamps are locked into their position for holding the materials in place. They are best to clamp together heavy and large projects.
