A gripper door and board carrier works by clamping onto the top or side of a sheet of material, providing a handle to carry it with. This allows just one person to carry sheet material that might otherwise be difficult to grip.
The pads automatically clamp onto the edge of a sheet as the handle is lifted. When the handle is loosened, and the weight of the sheet slacks, the clamp releases. Gripper carriers can be attached to any position along an edge of sheet material.
They can usually be used to carry sheets weighing up to 90 kg, depending on how much you can lift. They are available in different size ranges, so they can be used is various thicknesses of sheets.
