Clamp grip door and board carriers are heavy-duty carriers.
Handle
The handles of clamp grip door and board carriers are usually coated with rubber or plastic for a comfortable grip. Most of these carriers have a single handle, but some have a T-bar handle, so they can be held by two people, or with two hands.
Clamping grips
The clamping grips of these carriers are shaped in such a way that they will pivot open when pushed down onto a sheet and clamp shut when they are lifted. The distance apart at which they’re set will determine the thicknesses of materials they can be used with.
They are positioned so they can be used to grip a sheet from the top or from the side. They can be clamped onto any part of the edge of a sheet, so they can be held comfortably in various positions.
Once they’ve been unclamped, the grips automatically return to their resting position, as they’re spring loaded.
Joining bolts
Each clamping grip is joined to the handle with a bolt. The grips pivot on these bolts to move closer together or further apart, allowing them to grip different thickness of sheets.
Release cable
Some door and board carriers have an added cable which is used to open the clamping grips. This is designed to make it easier to attach and remove the carrier. It works by pulling up a trigger loop by the handle which pulls a cable up and opens the grips.
