Door and board carriers come in two basic designs: clamp carriers, which grip the top or side edge of a sheet, and base carriers, which support a sheet from below so it can be lifted. There are a few different types of clamping carriers.
Clamp door and board carriers
Gripper door and board carriers
Gripper door and board carriers clamp onto an edge when the handle is lifted, and hold it until the handle is released. These come in several sizes, for materials of different thicknesses.
They are specifically designed to make it easier for one person to carry sheet materials like plasterboard and plywood.
This carrier doesn’t have moving clamp parts; instead, it uses two stable rubber-coated gripping arms. They’re sold in pair as they need to be used by two people. They should be positioned so they go either side of the edge of the sheet, which is held firmly in position when the handle is lifted.
The heavier the sheet, the greater the grip will be. Two people, with a carrier each, one at either end of the sheet, are needed when lifting with this type.
Clamp grip carriers can be used to clamp onto the sides of a sheet to carry it. They can be moved along an edge and positioned for comfortable lifting. They have rounded clamps with a rubber coating so they have a soft grip.
They can be used by one person by clamping the top of a sheet, but they are usually used in pairs, by two people, as they are designed for lifting particularly heavy materials such as granite.
Carry clamps are usually designed specifically for lifting particularly heavy sheets of materials, such as granite slabs or glass panes. They clamp onto sheets when the handle is lifted. They can have either one or two handles.
These types of carrier are probably the most basic design. They have a lip, or plate, which goes underneath the bottom edge of a sheet. Then the handle is used to lift the material. The user’s free hand can be used to support the sheet as it’s being carried.
