Gripper door and board carriers are designed to clamp onto the edge of sheet materials and provide a handle to make them easier to carry.
When the handle is lifted up, with an appropriate sheet between the clamping pads, the clamp will close. The weight of the sheet works against the handle to keep the grip secured. The handle will usually have a rubber coating for comfort.
The pads have a relatively large surface area for clamping onto the edge of a sheet of material without marking it. They’re rubber coated to provide friction for gripping. The thickness each gripper door or board carrier can hold will depend on individual specifications.
The joining bolts of gripper door and board carrier attach the pads to the handle. The top one works as a pivot point while the bottom one holds the smaller pads at the correct angle for gripping.
