  • Device for carrying panel-like flat sheets
    Publication number: 20070046047
    Abstract: A carrying device for flat, panel-like objects. The device is a unitary construction comprising a pair of spaced apart straight legs connected by a cross bar at their top ends and a pair of panel supporting members. Each of the panel supporting members extends from a bottom end of the leg and is curved upwards. The external surface of the device includes multiple circumferential ridges that help provide a good grip.
