A panel hoist and components of various kits including components of a panel hoist are described herein. A panel hoist can be used to hold any of a variety of panels, such as a door attachable to a semi-tractor trailer, and to maneuver the panel for putting into a position for mounting the panel to a panel mounting point or for removing a panel disconnected from a panel mounting point. Various types of suction cups and supplemental panel holders can be used to hold the panel while the panel is moved or prepared for movement. A panel hoist can allow a single person to maneuver panels in various ways instead of having to rely on multiple people to maneuver the panel. Maneuvering the panel can include raising, lowering, or rotating the panel. Various panel hoist components can be configured as a kit.
